    Not that being near DC affords me any kind of right to an opinion, but:

    Given the uptick in near miss incidents across the US the last few years, this is the kind of incident that should've been entirely avoidable through changes in policy from these past events but is also apparently the only kind that can spur along policy changes. I can see a world where the fault is on the VH-60, but absent more information, it would surprise me less to hear that it's the fault of the tower.

    Knowing where AA5342 was in its approach, I see no possibility of the jet being at fault.

    I'm drawing a lot of early conclusions but it's mostly because I'm just not surprised. Angry as someone who flies a bunch, but not surprised.

      I just listened to the ATC recording from immediately before the collision. ATC instructs the helicopter to pass behind the CRJ. I’m fairly certain a few minutes before that, ATC instructed the helicopter to maintain visual separation, which is common. They typically ask, “do you have the aircraft in sight” and if you respond in the affirmative they rely on you to maintain safe distance.

      I should mention that in the recording you can only hear one side of the conversation, so I don’t know whether or not the helicopter said whether or not they had visual contact with the plane they collided with.

      Either way it doesn’t seem to be the fault of ATC. Of course we’ll know more as additional information becomes available.

        Here is the ATC audio between the Tower and PAT-25. Helos that transition DCA's airspace use a separate VHF frequency from traffic landing and departing, but talk to the same tower controller.

        https://archives.broadcastify.com/44114/20250129/20250129200...

        * At 5:41 - 5342 is given instructions for circling to 33.

        * At 6:45 - PAT-25 reports Memorial

        * At 7:06 - tower gives PAT-25 traffic advisory about 5342 and PAT-25 reports traffic in sight and requests visual separation

        * At 8:12 - tower asks PAT-25 if they have the CRJ in sight and tells him to pass behind the CRJ. PAT-25 again reports traffic in sight and again requests visual separation.

        * At 8:28 - crash occurs, exclamations, go arounds issued

          This is wild to listen to. A) this is a busy atc channel and it's amazing how much complexity is coordinated over noisy radio. B) within minutes of the accident happening (at 11:48) the ATC controller is calmly asking helicopters in the air if they can assist in search rescue operations asking, if they have search lights and direction them. This is whilst diverting and grounding flights.

            > over noisy radio

            I've been told the noise on the recordings is always a lot worse than in practice due to the location of the recording antenna not being ideal. I have no idea if this is correct or not. Maybe someone can enlighten this.

            • FL410 7 hours ago

              Yep. Radios are much clearer in the air. VHF is mostly line of sight and planes have the benefit of altitude. Approach/center comms can get a bit scratchy at times mostly due to distance, but approach/tower is almost always perfectly clear.

              • thowawatp302 13 hours ago

                Yes, having tried to listen to ATC with an SDR— the public recordings are made from antenna that placed near the airport, while the official recordings are made from the feeds that the ATC is listening to— and those antenna have their lobes pointed toward the sky.

                • jillesvangurp 6 hours ago

                  I watch a lot of pilots on Youtube. Most of them use some kind of audio splitter to record sound. You hear what the pilot hears. But minus the plane noise, vibrations, etc (unless that's mixed in via some open microphone). So, it's actually better.

                  So, it really is that bad. Especially when flying low, on the edge of the range of the radios, etc. VHF radio is ancient technology. It's not great even under ideal conditions.

                  If your phone calls sounded that bad, you'd want to upgrade your phone or switch operator. Really not acceptable for consumer grade communication. Not even close. This is how phones sounded half a century ago. "can you hear me .... are you there ..... can you talk louder ....". My grand mother never really unlearned 1930s phone etiquette. Phone calls with her were short (cause expensive) and she'd be shouting at you because that's what you did. Be brief, loud, hang up as soon as possible. That's what pilots still do. My grand mother was born during WW I (not II) and she's been dead for nearly 20 years.

                  The aviation world is very conservative with new/better/any technology. They stick with "what works". Even if arguably it barely works. Like pretty much the vast majority of radio exchanges between pilots and controllers over VHF radio. Learning how to talk on the radio is the second hardest part of getting an instrument rating. The only thing that's harder is flying a plane with zero visibility ... while suffering extreme information overload because of the constant radio chatter and dealing with confused/stressed/pissed off controllers who have to juggle you and 20 other planes.

                  A lot of radio exchanges are routine exchanges that involve very basic information: call signs, transponder codes, codes for approaches/departures, courses, altimeter settings, altitudes, weather information, etc. And then a lot of double checking the other side heard correctly, repeating back what you heard, etc. Radio communication compensates for the lack of a more robust/sane way of exchanging information. There literally is no way for a controller to send you information in written format. Other than using their private phones. So, it all gets spelled out over low quality VHF radio.

                  There's no good technical reason to not do something vastly more reliable, less intrusive, and less error prone. Some might say safer. Many planes have star link connections these days. The passengers get better connectivity than the pilot. They could be having video calls with the controller with crystal clear audio from anywhere on this planet instead of yelling to them over VHF only when they are in range. They could be sending each other emails, documents, digital maps, and lots of other machine readable information, etc. Not a thing.

                  It's more a challenge of agreeing on what such a vastly better thing would be and then updating each and every plane and tower, airport, controller world wide with equipment that supports that. Add design by committee to the mix and the "state of the art" is something that would make any competent engineer born after 1970 blush.

                    No, landlines in 1975 sounded outstanding. I didn’t hear the phrase “can you hear me now” until I got my first oki (1992?)

                      YouTube is not a good representation of what you hear in a headset. Half the time the mic taps aren't impedence matched and sound like shit.

                      Besides that, most "controlling" (i.e. instructions that require action) comms have a handshake of sorts - the pilot repeats back the instruction for the controller to confirm. They don't just bark out instructions and hope you heard it, they listen for you to read them back, and will keep doing so until successful. So, even in cases when the comms are degraded, you will go back and forth until there has been positive confirmation (readback) you heard the instruction correctly (or they'll just give you a new frequency).

                      • jcrawfordor 4 hours ago

                        Honestly a lot of those recordings probably do sound a lot worse than the radio audio. I rarely see YouTube recordings that are as audible as the radio is in person. Here's what seems to be the reason:

                        The common splitters you can buy to break out your headset connector to a recorder don't account for the signal level, which is very high on the headset connectors as aviation headsets are traditionally pretty high impedance. I've struggled with the headset audio blowing out even a fairly nice recorder (a Zoom) with the gain turned all the way down. Phones and pocket reporters don't even offer a gain adjustment and the recording can end up almost unusable. In a lot of YouTube videos of pilots, even most, it's pretty obvious that it's clipping at the recorder the whole time. Perhaps even worse, a lot of people are using like a GoPro with auto-gain, so you get the worst of both worlds: it ramps up gain until the noise is loud, and then when someone starts talking, it ramps down the gain, but a little too slowly, and it's still clipping even when it hits minimum.

                        It's not very common to have trouble understanding the controller when in the air. AM radio at line of sight (as is the case when you're flying) is pretty robust. Maybe the hardest thing to understand are helicopter pilots because there's often rotor noise on their end.

                          They are also in a fairly standardized format with reserved "keywords" for many important aspects of operation ("hold short", "line up and wait", "cleared to X"):

                          English is the lingua franca of ATC, but it is recognized it is obviously not everyone's first language.

                          • V99 3 hours ago

                            Besides the "we already have it everywhere" bit, the big advantage of analog AM over UHF/VHF is that it degrades fairly gracefully. As you're getting too far away the signal gets harder to pick out from the noise, but it's not an all-or-nothing digital signal.

                            That doesn't matter much over Washington DC, but when you get out towards the western half of the country the transmitters are a lot more widely spread out. There's mountains in the way. There's limitations to how low you can be and still be reachable, which sometimes has to be balanced against how high a GA plane can comfortably fly, or oxygen requirements for the occupants.

                            A better sounding "modern" system is generally going to be worse at handling those marginal situations, which would probably require building a lot more radio outposts in fairly remote areas to compensate.

                            But the big problem with requiring anything new is getting it into the existing fleet of thousands of decades old certified aircraft. You need a new radio stack. You probably need new antennas. Changing anything on certified aircraft needs tons of paperwork and things like Supplemental Type Certificates for each individual model of aircraft that make it cost 5-50x what you'd think it should cost. Military aircraft are probably 10x worse beyond that.

                            A handheld COM radio is maybe $200 from Sporty's. Take basically the same thing but package it as a basic Garmin COM radio (GTR 205) and it's now $2,300. If you want a NAV radio in it too (GNC 215) now it's $5,400. Add GPS and ADSB-Out (GNX 375) and now you're at $9,000. You can buy an entire currently airworthy (really old) plane for maybe $30,000.

                            For some uses you don't even have to have any radio or transponder/ADSB installed on your aircraft. Some aircraft don't even have an electrical power system to run one. Granted they're not allowed in the middle of Washington DC, but still trying to require the entire fleet gets fancy new digital radios would be a monumental challenge and fantastically expensive.

                            There are some existing better ways to communicate. Larger planes usually have CPDLC (Controller Pilot Data Link Communications), which is basically text messaging from ATC to the plane avionics. That's how they receive their IFR clearance at major airports. In an airliner you're not generally reading it out over the radio and scribbling out your "CRAFT" acronym on a scratchpad like you see on YouTube. (Even your 4-seat steam gauge Cessna can do this via PDC (Pre-Departure Clearance) at supported airports with something like ForeFlight on an iPad).

                            CPDLC can also be used in the air to communicate less time-sensitive things like altitude changes and reroutes, talking to the operations department of the airline, etc. There's no reason you couldn't put this in smaller GA planes and towers, other than cost.

                            Airliners that do transatlantic and -pacific routes also have satellite communications instead of using old-school HF radios (which are even worse than VHF).

                        In the video from the webcam there's another plane which is much easier to see. Could they have asked about "the aircraft" and the helicopter pilot mistook which one they referred to? "yes I can see the plane flying much higher"

                          It's possible but generally there's implied context to ATC. ATC would only instruct you to watch out for possible vector interceptions. flying over an approach path, the context would be that you would look for aircraft on approach, not ones in holding or other patterns above.

                          That said, it's possible they mistook which aircraft to look for, but it's unlikely imho and we will likely never know for sure, as I would presume the pilots are deceased.

                            I got a lesson in how ATC works with helicopters up close and personal on a helicopter tour. ATC had the helo pilot hold position while an airplane was on final approach. I asked the pilot why we needed to hold as we could clearly see the aircraft and were to my lack of knowledge on the subject "plenty" far away. (It actually took me a second to locate the airplane as my sense of scale was not expecting the plane to be so small which is part of why I made the assumption we were plenty far away.) That's when the pilot told me we were not in the way of the approach but if the pilot had to declare a miss (or whatever they call it) and climb to circle around. The helo was near the path for the plane on the abort flight path. Once the plane was on the ground, ATC allowed us to continue.

                            It was my first experience in an aircraft seeing how ATC controlled the airspace directly. Lots of respect to the folks in ATC with a fraction of understanding in just how much they have to deal with other than the obvious take-off/landings.

                                    Marine radar is trivial compared to air-to-air radar. The Black Hawk, like most aircraft, does not have an air-to-air radar. IR cameras would be completely inappropriate for the situation but night vision goggles are a possibility I guess - though still have all the same drawbacks as using your eyes - you have to look in the right direction and recognise what that small dot is that you’re seeing.

                                  The common mistake with this is seeing a plane, reporting "traffic in sight" but looking at a different plane than the one the controller meant. Especially at night where distance is near impossible the estimate and you can't see differences in types of planes.

But as I posted, we should not have this happen anywhere in the United States in 2025 & much less the nation's capital. Hopefully DOT and FAA get to work, but I have a feeling that will be the end of DCA's usefull life as a major passenger airport.

                                                      From what I have seen, if a worker agress to it, they agree they could be reassigned or terminated early (and thus not paid the same or at all). Seems like a trap.

                                                    Do you think people should be electing the ATC agents?

                                                    Also, what’s your opinion about the entire cabinet, Elon Musk, and the likes, all of whom are also unelected?

                                                  Also DCA is the most popular airport and congress would stage their own revolution if they had to go further.

                                                    Yeah, it's at least partially Congress's fault DCA is as busy as it is. Every few years, they push to allow more flights, and longer flights, into the airport, because they all want to convenience.

                                                    Which is silly, it's not like IAD is all that far away. It's a straight shot down the Access Road to 66 and then into the city. Of course, with the RTO mandate, the portion from 66 inward is going to get busy again, but hey, Congress wanted that too, so reap what they sow, I suppose.

                                                      DCA is much nicer in pretty much all respects other than having a fairly restricted set of routes. When the routes are available, I’ll pick DCA every time. It’s a gem, and I’m glad that Congress’ selfishness overrode their terrorism paranoia on this one.

                                                      • alistairSH 5 hours ago

                                                        That's true, DCA is smaller footprint, so easier to navigate inside. And even better now that the remote terminal redone and linked properly (vs the old "Take a bus and wait on a bench").

                                                        But, the last few years, I haven't had any issues at IAD. Yeah, it takes longer to get from the front door to the gate, but that's about it. The security lines are more reasonable now (pre-COVID they were pretty long at times).

                                                        I pick IAD when I can, but that's only because I live in Reston. If I lived inside the Beltway, I'd pick DCA, but only because of the shorter drive, not the airport experience itself.

                                                        And I wouldn't want DCA to be shuttered. But, it's been at capacity for a while and Congress keeps pushing that limit.

                                                      I definitely think it’ll stay open for charter flights (part 135)

                                                        it’s actually really hard for private jets / charter (whether part 91 or part 135) to use dca. requirements include having an armed officer on board. as a result almost nobody flies charter into dca.

                                                        I only have a passing interest in this, but DCA's approach is tricky, the airspace is complex and restricted, and then you mix in military pilots doing VIP helicopter training runs across the approach. The procedures make it safe-ish, but it's riskier than other major airports.

                                                    • hammock 6 hours ago

                                                      I was a controller at DCA for 8 years and this is a normal operation with Helicopters using the Helicopter routes.

                                                      The problem I see is the controller asked the Helicopter if they had the CRJ in sight, but he never said WHERE HE WAS OR WHAT HE WAS DOING! The controller should have told the Helicopter that the CRJ was circling to RWY 33. The helicopter said he had him in sight, but he really had the Jet in sight that was landing on RWY 1.

                                                      Had the controller told him: Traffic ahead and to your left landing runway 33 is a CRJ report him in sight, then the helicopter crew would have LOOKED to their left and saw him. They unfortunately were looking straight ahead at a different plane.

                                                      The controller is going to take a major blame for this one unfortunately for not being more detailed. Those Helicopters literally fly directly in the path of those RWY 33 arrivals so as a controller you have to be EXACT!!!!

                                                      Another problem I see is the expectation bias. As controllers in that scenario, we want to hear the Helicopter say "traffic in sight and we will maintain Visual Separation. These Helicopter Pilots know we need to hear them say that (it's required), so they will say this just because even though they might not really have the aircraft in sight. They are just saying what we want to hear. If they don't, then we stop their forward progress or make them turn out. Comment from instagram

                                                                          Trump is explicitly blaming programs to hire disabled people. Note that just because FAA had a program to hire people with disabilities, does not mean that they made any changes to the medical standards for air traffic controllers - there are many jobs at FAA besides air traffic controllers, and there are also plenty of disabilities that would not effect a person's ability to be an air traffic controller. FAA does not allow people with psychiatric disabilities to work in ATC.

                                                                          > “I do want to point out that various articles that appeared prior to my entering office. And here’s one, the FAA’s diversity push includes focus on hiring people with severe intellectual and psychiatric disabilities. That is amazing. And then it says FAA says people with severe disabilities are most underrepresented segment of the workforce said ‘they want them in, and they want them, they can be air traffic controllers. I don’t think so. This was January 14, so that was a week before I entered office. They put a big push to put diversity into the FAA’s program,” Trump said.

                                                                          > “Brilliant people have to be in those positions, and their lives are actually shortened, very substantially shortened because of the stress where you have many, many planes coming into one target, and you need a very special talent and a very special genius to be able to do it,” the president added.

                                                                          > When he was asked to clarify why he thought a “diversity push” at the FAA played a role in Wednesday’s collision, President Donald Trump told reporters Thursday that “it just could have been.”

                                                                          > “It just could have been. We have a high standard. We’ve had a higher, much higher standard than anybody else,” Trump said.

                                                                            On "Truth Social" last night, Donald Trump was explicitly questioning the actions of the ATC. And during this morning's press briefing, he blamed "the crash on Barack Obama, Joe Biden, former Transportation secretary Pete Buttigieg, DEI and people with disabilities." I'm waiting for the transcript on that one.

                                                                            • axus 4 hours ago

                                                                              ----

                                                                              President Trump also appeared to blame a “diversity push” at the FAA for the midair collision, reading some news headlines.

                                                                              “I do want to point out that various articles that appeared prior to my entering office. And here’s one: the FAA’s diversity push includes focus on hiring people with severe intellectual and psychiatric disabilities,” Trump said.

                                                                              When he was asked to clarify why he thought a diversity push played a role, he said, “It just could have been. We have a high standard. We’ve had a higher, much higher standard than anybody else.”

                                                                              Trump did not cite any evidence.

                                                                              He also placed blame on the Biden administration’s transportation secretary, Pete Buttigieg, using an expletive to describe Buttigieg’s time in office.

                                                                              “He’s a disaster now. He’s just got a good line of bulls—,” Trump said of Buttigieg. “Well, he runs it, 45,000 people, and he’s run it right into the ground with his diversity.”

                                                                              Trump’s pick for transportation secretary, Sean Duffy, who just started the job, also spoke during the press conference.

                                                                              “When Americans take off in airplanes, they should expect to land at their destination — that didn’t happen yesterday,” Duffy said. “That’s not acceptable, and so we will not accept excuses. We will not accept passing the buck.”

                                                                              • dboreham 5 hours ago

Or are all the white men just doing that great of a job compensating for their dumbass POC/non-male colleagues? It's not like this is a team effort where one competent employee can cover for others; if an ATC is genuinely unqualified, shit is going to go wrong immediately.

                                                                                    Your grievance politics are nonsensical on their face.

                                                                              • derektank 18 hours ago

We shouldn't give equal respect to the Federal Aviation Regulations and to OPM's Qualification Standards for Federal Jobs; doing so deligitamizes the importance of the former.

                                                                                  So where are all these specific regulations that are so terrible and the evidence that they are indeed net negatives.

                                                                                  I absolutely believe such regulations exist. But that’s not what these people care about. They simply care about trashing the govt to make it easier to drown, otherwise they would actually act like the YIMBY movement and identify specific regulations and work on changing those.

                                                                                  • RHSeeger 9 hours ago

Some are important and put into place because people died without them. Others are put into place for less important reasons. And the fact that _some_ regulations were removed doesn't mean that "ones written in blood" necessarily were.

                                                                                    There are definitely regulations out there written by people that have no idea what they are talking about, and that are a net negative on the area(s) they impact. Does that mean we should remove Chesterton's Fence? No. But it does mean that, if you see someone removing a fence, you shouldn't immediately accuse them of causing harm.

However Boeing changed and put other priorities first and started cutting corners but their reputation was still good. After all, why would Boeing (unlike, say, tobacco) sell products that would kill their customers: it would be against Boeing's own interests.

                                                                                                In the 1980s and 1990s Boeing could be trusted to have less oversight, but since the 2000s that was no longer true, but no one noticed that. Now everyone recognizes that Boeing needs a babysitter.

I agree there's a certain amount of theater, and I try to avoid really peak times, but with pre-check I do tend to arrive early because I don't want stress but, as you say, it's rarely more than a few minute wait and I pretty much toss my bag on the carousel and walk through the metal detector. It's really not a big deal if you're prepared.

                                                                                                                          In my area they all want you to arrive 2-3 hours before your flight, without any water, then to shuffle through security without your belt and shoes.

                                                                                                                          • ghaff 6 hours ago

For one thing, my car company doesn't really want you to cut things close as they'll tend to catch the blame if you miss your flight for some unavoidable reason. But usually security is maybe 5-10 minutes. Don't remember the last time I needed anything like the margin that I give myself.

                                                                                                                            Probably doesn't hurt that I'm usually taking early morning flights.

                                                                                                                              It's not a huge time-saver (any more, used to be more) but gets you out of a few annoyances like removing shoes, unpacking toiletries, and a few other things. And the lines are usually a bit shorter and the ratio of regular traveller to new traveller is a bit better (less likely to get caught behind somebody who doesn't know the process and wastes everybody's time).

                                                                                                                              • ghaff 6 hours ago

I have pre-check automatically through global entry (that basically lets you bypass immigration coming back into the US).

                                                                                                                                Just got ETA for the UK and you also have e-entry (which usually works) from the US and a number of other countries as well.

So for those of that fly with film camera gear, we need a hand check with or without pre-check.

                                                                                                                                  • ghaff 6 hours ago

This makes take offs and landings at DCA challenging since all this restricted air space has to be avoided. DCA also has not space to expand to try to mitigate the risks. Congress has interfered over the years by attaching riders to legislation requiring the number of flights allowed in and out of DCA to be increased over the objection of the Metropolitan Washington Airport Authority (MWAA) who runs both DCA and IAD (Dulles). This despite decades of warnings that the number of flights posses a significant safety risk.

                                                                                                                        Regional airport authorities which run multiple airports such as MWAA generally spread the cost of improvements out across the multiple airports by increasing gate fees at all the airports they control to cover the cost of improvements at any one airport. Congress has forbidden MWAA to do so which has limited their ability to expand and improve IAD to lure airlines to shift domestic flights from DCA to IAD. IAD remains primarily an international airport with domestic flights in and out supporting that role. This is largely due to the higher gate fees at IAD.

                                                                                                                        • jonstewart 17 hours ago

Dulles now has a Metro station, but it's still far away from the terminal and it's hard to navigate, with gates very far away from the terminal; other than the Saarinen architecture, everything else about Dulles is awful. BWI is even further from most parts of DC; there's an AmTrak station where you can catch a bus, but pretty much you're driving an hour+ and it's in the middle of exurban hell.

                                                                                                                          DCA is challenging for flights, though, as the approach from upriver over the Potomac requires a sudden bank to the right just before landing and the runway's a bit short (tonight's flight was coming in from the southern approach). The Potomac also has a lot of helicopter traffic, between the military (including POTUS/VPOTUS), US Park Police, DC Police, and civilian flights. DCA's natural advantages have put the screws to Dulles the last 20 years, and Dulles's inability to not suck hasn't helped. As a result, people (including Members of Congress) want more flights out of DCA, so flight traffic has steadily increased. There were two near-misses last spring: https://www.nbcnews.com/news/us-news/faa-investigating-colli....

                                                                                                                          Tonight's crash seems like a colossal screwup by the helicopter. DCA is too popular for flight traffic to cease, but I wouldn't be surprised by further restricting the flight corridors and helicopter traffic, more funding/staffing for ATC, and maybe a small reduction in flights.

From an administration that is currently doing its best to get rid of as many federal employees as possible and has an extra "department" (led by you-know-who) dedicated to that? What they will probably do with ATC is privatize it (which is actually a reasonable thing to do - it's private in most of Europe, but if the intention behind it is to save money, it will probably not improve the system).

All the YT comments say it's because it's privately controlled and understaffed and many pilots vouch for similar drama happening to them. I can't prove it, just passing along a data point. Obviously this problem could be solved by paying better and having enough staff. But how likely is that?

Noted elsewhere, it's a bit easier to navigate internally (smaller, newer terminal building vs IAD), though I don't know how much that impacts Congressmen - I'm guessing they at minimum are using first class/preferred facilities and not queuing up with us plebes for security.

                                                                                                                                        Periodically, Congress pushes to have DCA take more traffic total and from a larger portion of the US. Currently, DCA is limited to destinations 1250 miles away, though powerful Congressmen have obtained permanent waivers for this over the years for specific flights so they get an easy flight to their own home region.

I have a warm spot in my heart for Dulles, because it's my first memory of American (we flew into Dulles from Bangladesh in 1989). It's really convenient if you live in Great Falls or Reston. And I loved what was then the semi-rural Virginia around the airport. But agreed, it's a huge pain in the butt to navigate.

My biggest objection to EWR is that it's a PITA to get into Manhattan from but, then, that's pretty much true of all the NYC airports. I'm rarely doing that though as I'm almost always taking the train into the city.

Also, the airport is surrounded by lots of restricted airspace because, you know, seat of federal government and all that.

                                                                                                                                      It was discussed post 9/11 about closing National Airport, but congress wouldn't hear it. It was too convenient from DC. (At a time when IAD was way the hell out there, rather than being 1/2 the way out the sprawl.)

                                                                                                                                      I won't fly through DCA in the winter, because when I was a kid there was the Air Florida crash. I'd much prefer IAD with it's 3 mile runways and straight approaches.

Fortunately, de-icing procedures have also improved since then - in the 80s, it was possible to have a long time between deicing and takeoff; today, deicing is done at the end of the runway, shortly before lining up for takeoff.

It was a shitty day all around -- there was a metrorail accident under the river. I was on a school bus for 4 hours while getting home in the snow. The plane hit a bridge and went into the river.

                                                                                                                                          Think of what you know about DC traffic when there's a flake of snow in the air, and put an airliner crash and a metro accident on top of that.

                                                                                                                                          Maybe it's not logical, but I'm still not a fan of flying through National in the winter.

                                                                                                                                We like to throw shade at Boeing, the FAA etc, but this is still an incredible accomplishment, especially given the explosive growth of traffic over those years. Back in the 1970s and 1980s, there were far fewer flights but multiple crashes every year was the norm.

The FAA Admin (Michael Whitaker) who was forced out started serving in Oct 2023. The TSA Admin (David Pekoske) was first appointed in 2017, and then nominated for another 5-year term in 2022.

                                                                                                                                                unions make sense for private organizations because private organizations are effectively authoritarian entities, not democracies. there is no mechanism in which you could actually "vote" anyone out or establish a leadership position by virtue of popular support, and most importantly there's no constituency to air grievances to

They're just jobs, no one votes for them beyond in some cases voting for the head of their agencies but more often by voting for the people that will select the agency heads.

                                                                                                                                                    Let’s not make stripping away of freedoms a common thing that employers, government or private, can do. Rights are rights.

Unions are supposed to be an adversary of management who they negotiate with, and depending on who wins the election they are an ally. There's a conflict of interest. So naturally the group that supports the person that wins the election will have a favorable contract and be able to grow their union as that's beneficial to the political party and the union.

                                                                                                                                                          At the very least states should implement laws and statutes that define limits and rules such as union compensation must be paid with the current years revenues and not with bonds that are paid for by future generations, etc.

The 'good guys' at Boeing were pushed out or silenced, the 'sleazy guys' won and didn't care about the consequences as long as they got their payday

I trust that like other major accidents, that we will learn from this and make the skies safer. Sixteen years without a major airline crash was an incredible accomplishment. It's a tragedy it couldn't have gone on longer.

And the FAA absolutely refused to do their job until their hand was forced by everyone else - they refused to ground the Maxes until all other major air authorities did. That's also why EASA is involved in the Max recertification, and the 777X certification. Nobody trusts the FAA anymore.

                                                                                                                                                                And the fact that the door blowout didn't damage any part of the plane is miraculous - if it had hit the vertical stabiliser, the plane would have been a total loss.

                                                                                                                                                                So you're giving credit where very little is due.

                                                                                                                                                                    if you look at [0] it has tracks of both flights. toggle the right-hand sidebar, if it's not open already, and you'll see a table containing both planes. the helicopter (PAT25) is yellow, the plane (JIA5342) is blue. the legend right below that explains the color-coding - the plane's data came from ADS-B, while the helicopter's data came from multilateration (MLAT).

                                                                                                                                                                    MLAT [1, 2] works by having multiple ADS-B feeder stations cooperate in real-time and deduce an aircraft's position based on timestamps of when the signal is received. it allows tracking aircraft that only broadcast the more limited Mode S data, instead of the newer and more detailed ADS-B.

                                                                                                                                                                    because it requires multiple cooperating receivers, the start of the track in suburban McLean does not mean it took off from there. it just means that was the point in its flight where it became visible to enough receivers that MLAT was able to pin down a position.

                                                                                                                                                                    you can also see this difference just by looking at the tracks - the plane is broadcasting its own position continuously, so its track is nice and smooth. meanwhile the helicopter's flight looks "jagged" in a way that does not match what its actual flight path would have been. this is an artifact of the small errors introduced by MLAT.

Then you just write a python script to keep an eye on colliding trajectories.

ATC was literally mid conversation with the helicopter to deconflict it's path when the collision happened.

                                                                                                                                                                              What is it with people insisting that the smart people literally tasked with their job somehow have no idea how to do it?

                                                                                                                                                                        [2] shows the helicopter taking off 2 miles away from the old saudi embassy in McLean marked “permanently closed” on google maps. (The current embassy is in DC proper, directly across the river from DCA airport)

                                                                                                                                                                        I don’t think thats strong evidence that it took off from the old Saudi Embassy - thats pretty far away even given your caveat about accuracy.

                                                                                                                                                                        Edit: it looks to me like the black hawk was coming from somewhere else with its ADS-B turned off entirely, and then turned on ADS-B once it reached the potomac to approach DCA. The first two datapoints of that flight already show it going 110mph, which its unlikely to be able to accelerate to in just 0.2miles after take off.

                                                                                                                                                                        Edit 2: The route also looks very similar to this flight from 11 days earlier (but reversed in direction): https://www.flightaware.com/live/flight/PAT25 This shows the Blackhawk at 300 feet passing by DCA on what seems like a routine or training flight? I don't know how to look up historical flights to see if this is a commonly-flown route. On that flight, the Black Hawk flew past DCA at 300 feet of altitude, and the last FlightAware data for the American Eagle passenger flight showed 400 feet of altitude.

The flight track starts at the backyard of a house that is currently owned by the embassy. You can see the owner of that property by searching that address here (the site doesn't support a direct link): https://icare.fairfaxcounty.gov/ffxcare/search/commonsearch....

It gives a lot of information on how the two aircraft should have been able to share the space and some speculation on what went wrong:

The VH-60 variant is just a UH-60 that was build/configured for VIP transport vs the normal UH-60 utility variant.

I once read a scale of language proficiency that placed "Can converse over a poor phone connection" at a very high level. When a word is garbled or lost, you have to quickly think of all the possible words that could've fit the grammar and whatever sound you heard, consider them in the context, and choose one or two. Then the next part of the conversation should let you pick one. Then add the complication of not seeing body language.

                                                                                                                                                                                                            I forget where I read this. I think it was from the US Department of State, but I can't find it now.

As of 10 am EST today there was a moderate police and rescue presence on the water. There is a significant amount of debris visible floating in the river, and the boats are fishing it out piece by piece. The only things in the air are a handful of helicopters, presumably related to the search operation.

                                                                                                                                                                                                            • snowwrestler 9 hours ago

                                                                                                                                                                                                              DCA has two runways. The longer runway is aligned with the river’s north/south direction at that point, so planes flying the approach to this runway from the south track along the western shore of the river, leaving the eastern shore clear for other aircraft like helicopters. The vast majority of flights on approach from the south [1] use this longer runway.

                                                                                                                                                                                                              The secondary runway is set at a diagonal NW/SE. Planes flying an approach from the south follow the river at first, but then loop out over the eastern shore of the river to line up on that runway. To my eye the radar track of the downed flight follows this path. It’s possible since it was a small plane and only small planes can use the diagonal runway—it’s shorter.

                                                                                                                                                                                                              I mention this because this track takes planes into airspace that is a) usually clear of commercial airplane traffic, and b) directly over military facilities like Naval Research Lab and Joint Base Bolling, which have significant military helicopter travel.

                                                                                                                                                                                                              Basically, I wonder to what extent the helicopter pilot was surprised to find an airplane descending in that location.

Approaches to the diagonal runway from the north take planes almost directly over the Pentagon.

I wonder if the helicopter crew were not fully briefed on the new path, if that is the case.

Can confirm that it is not unusual for flights to pass directly overhead of us, however I don’t understand the statement that this was a new flight path.

This required a "jog" in flight path -- a slight right turn followed by a left turn, to account for the different orientation between the runways. You can see the turns on the ADS data. Crash happened right at the end of the second turn.

                                                                                                                                                                                                                    • francisofascii 7 hours ago

                                                                                                                                                                                                                    • nradov 19 hours ago

Flight volume has been growing, airspace near airports is more congested, and controllers are overworked. Eventually all of the "Swiss cheese" holes line up. We're going to need to hire more controllers.

                                                                                                                                                                                                                      Also, it appears that one of the aircraft was a military (not police) H-60 Blackhawk helicopter.

A friend's daughter just went through the hiring process. She graduated from college with an appropriate degree right as COVID hit. Her FAA application wasn't accepted for four years.

                                                                                                                                                                                                                        This past summer she did the four-week interactive online courses. Applicants must pass this and may not re-enter the program if they do not. After that she did the six-week courses in Oklahoma City. Again, applicants must pass this and may not re-enter the program if they do not. She passed. Only half her class of 20 passed. In the prior class, only 4 of 15 passed.

                                                                                                                                                                                                                        She declined the position when they could not offer a position within reasonable proximity of her family. She, too, may not re-enter the program. On top of all that, the program has strict age requirements because there's a mandatory retirement age (55, I believe).

                                                                                                                                                                                                                        There isn't a large pool of applicants and the percentage of successful ones is not high. Considering the amount of lives on the line, it's understandable the hiring criteria is strict. All told, it's not an easy position to fill and even explicit efforts to increase the number of applicants will take years. Just like many other skilled fields.

                                                                                                                                                                                                                                Probably not much, considering the biggest constraining factor is pay. For example, San Carlos airport is shutting down ATC entirely because they can't pay anyone enough to live locally to the tower: https://www.kron4.com/news/bay-area/bay-area-airport-losing-...

                                                                                                                                                                                                                                There would be no problem filling the seats if the compensation was handsome and attractive. But we all know how federal workers are compensated, even when lives are on the line.

With most making 140-150, and many making up to 200k.

                                                                                                                                                                                                                                  I could see this maybe being an issue in the bay area but outside of that area that pretty good pay.

They explicitly structured things so that ATC hiring was pre-restricted for non-cognitive (e.g. merit) reasons, and failed out candidates that scored a perfect score on the cognitive test on the basis of their demographics (they weren't minorities).

                                                                                                                                                                                                                                  • talldayo 4 hours ago

                                                                                                                                                                                                                                    ATC (as well as most government jobs) are a real case of "you get what you pay for". When you bring wages down so low that educated engineers don't want to work your job, your options are to lower the qualifications or leave empty seats.

                                                                                                                                                                                                                                    DEI might have contributed to this, but we wouldn't be hiring unqualified people in the first place if America could naturally compete for talent. The lesson learned seems to be less about the dangers of diversity and more about how the feds aren't paying the industry rate for professionals.

Controllers are operators, not engineers. There are some working controllers with engineering degrees, but almost nothing in typical engineering coursework is directly relevant to the job.

                                                                                                                                                                                                                                      • tristor 4 hours ago

Because in that link, what I am responding to, it EXPLICITLY says that the FAA changed the ATC selection process to exclude candidates based on demographics (being not diverse) regardless of their aptitude as tested using a standardized and validated cognitive assessment. These were candidates who had already completed multiple years of schooling and explicitly wanted to be ATCs, so you are talking about a pipeline problem which may or may not exist but is irrelevant to the article I am responding to in the link above my comment.

                                                                                                                                                                                                                                        Per that article, candidates who accepted the pay terms and wanted to become ATCs were /rejected/ explicitly because they were not minorities or otherwise able to produce a biographical or demographic reason for acceptance, even when they scored a perfect score on the standardized aptitude assessment.

                                                                                                                                                                                                                                        If you have something to refute the article the person above me linked, I'd love to see it because I'm incredibly disappointed in what I read about in that article.

                                                                                                                                                                                                                                          Except that none of the plaintiffs in the lawsuit actually bothered to apply for jobs with the FAA (see this blog post from their own legal team crowing about winning a procedural matter over whether they had standing to sue given that they never applied for a job and thus were never actually rejected by the FAA https://mslegal.org/press-releases/mslf-prevails-over-faas-a... )...

                                                                                                                                                                                                                                          What actually happened was that the FAA invalidated a bunch of AT-SAT[1] scores to align with its new diversity policy, and a bunch of people who barely passed the first time didn't want to re-take the test again and risk failing. So they did the American thing and sued instead.

                                                                                                                                                                                                                                          The FAA has not rejected qualified candidates on the grounds of "diversity." And at any rate, the controller in the DC tower last night was hired during the Trump administration and the Blackhawk pilot that caused the crash wasn't the kind of candidate who would have been selected on DEI grounds...

                                                                                                                                                                                                                                          [1] it's like the SAT, but for controller jobs instead of college admissions

Another commenter points out that this practice ended in 2018 due to Congress making it illegal, but prior that the FAA had been issuing a biographical assessment as a basis for hiring decisions, exactly as stated in the article.

                                                                                                                                                                                                                                            Your own link has the court opinion confirming my understanding of the article. The fact they won the case on procedural grounds is not relevant to the fact the court is opining in the case that the evidence supports a conclusion that the FAA discriminated against "non-diverse" candidates who were otherwise qualified.

                                                                                                                                                                                                                                            I think we can all agree that for a role like ATC, the most important thing is that candidates are competent and capable, because it is literally life or death. I have the strong belief that minority candidates are also competent and capable, so discriminatory against "non-diverse" candidates is reprehensible in the strongest terms. I don't think my position here is unusual, unreasonable, or in any way objectionable, and it turns out Congress agreed and made this practice explicitly illegal.

                                                                                                                                                                                                                                            If I'm hiring for a job where there's a strict requirement to be 6 feet tall and there's nothing candidates can do to get taller - then once you've measured under 6 feet there's no point in re-testing you.

                                                                                                                                                                                                                                            If I'm hiring for a job where there's a strict requirement that you be able to lift a 90 lbs weight, a lot of people will fail - but if they hit the gym, in a month or two they'll be able to pass easily.

                                                                                                                                                                                                                                            If I'm hiring for a job where there's a strict requirement that you be able to lift a 90 lbs weight, but before the test every applicant goes through a 6 month strength training program, so we test them at absolute peak strength? Re-testing would be a waste of time, except in a few cases like if someone had a loved one die just before the final test.

                                                                                                                                                                                                                                            If I'm hiring for a job with a written test, the test draws a random selection of questions from a question bank, and some questions are much easier than others? There might be a substantial random element to the results. If re-testing people produces substantially different scores, probably that indicates I need to improve the design of my test.

The tower will be unstaffed.

However, the contract does not include locality pay to account for the high cost of living in the San Francisco Bay Area. As a result, RVA’s employment offers to current SQL controllers were significantly lower than their current compensation under SERCO. Understandably, all current controllers have declined RVA’s offers."

                                                                                                                                                                                                                                                              "Given that the FAA is ultimately responsible for ensuring air traffic services at SQL, we requested temporary FAA staffing for the tower—a solution currently being implemented at Eagle Airport in Colorado during its transition from SERCO to RVA. However, the FAA informed us this morning that they will not provide temporary personnel for SQL"

You can find plenty of threads about it on forums and on YouTube.

                                                                                                                                                                                                                                                                Now they want to go with an even bottomer-of-the-barrel contractor? That's not going to work at all.

                                                                                                                                                                                                                                                                  Doesn't that just mean there will be no taxi control? My understanding is that ATC isn't in the tower. The tower staff just give clearances for take-off and directions on which runway to land/take-off. In radio clips, you can hear ATC hand-off a plane to tower.

                                                                                                                                                                                                                                                                  • nharada 15 hours ago

They give taxi, takeoff, landing, and close in maneuvering instructions.

                                                                                                                                                                                                                                                                    When you say ATC I believe you’re thinking of tracon controllers, a level of airspace up from towers who control approach and departures and then hand you off to/from the tower. Above them there’s yet another level, center controllers. All of these are ATC though.

                                                                                                                                                                                                                                                                    • V99 13 hours ago

                                                                                                                                                                                                                                                                      The "ground" controller manages taxing around the "movement areas" (i.e. taxiways) on the ground. This notably does not include the runways. And it depends how much of the actual ramp and parking area they control (those are sometimes non-movement area and it's the pilots job to not hit anything).

                                                                                                                                                                                                                                                                      The "tower" controller manages the actual runways, and the airspace within several miles of the airport laterally and a few thousand feet vertically (varying at each airport). This includes sequencing all the planes that want to take off of land there, and everybody maneuvering around that immediate area.

                                                                                                                                                                                                                                                                      For the large airports that mostly big airliner flights, that sequencing is largely worked out by the approach controllers dozens or hundreds of miles ahead of time. So there's a steady stream of planes following standardized approach procedures at just the right distance apart.

                                                                                                                                                                                                                                                                      Outside of the ~30 busiest airports in the country though, there is also a lot of general aviation in small planes. They want to transition through that airspace, or do a dozen laps around the "pattern" to practice landings, etc. Even at fairly major airports, there's plenty of GA activity. For example at Burbank, Ontario, John Wayne, Long Beach, San Jose, Oakland, etc in California. It's only really SFO and LAX where that doesn't really happen, because they set fees to shoo the peons away.

                                                                                                                                                                                                                                                                      SQL is a small but very busy airport that is almost exclusively GA. There are several flight schools there with multiple planes each, and it's sandwiched in complicated airspace between SFO, SJC, OAK, and open bay.

                                                                                                                                                                                                                                                                      The tower at this kind of airport is doing a delicate dance keeping multiple planes buzzing around in a rectangular pattern all day every day. Some of which are faster than others. Less frequently a larger much faster plane wants to get in or out and they're getting handed off from approach. Helicopters are doing tours and wanting to cross through. And a lot of the people flying are students that are new at this, don't know how to talk or listen on the radio right yet, make mistakes following directions, etc.

                                                                                                                                                                                                                                                                      With the tower closed, all those people have to coordinate on a party-line radio with each other about where they are, what they're doing, etc to hopefully not hit anyone. So yeah... it's possible, but it's going to be a mess, and that's why tiny airports like this with virtually no commercial passenger service have a tower.

                                                                                                                                                                                                                                                                      Also if you're leaving the immediate area, someone at the airport (ground, tower, or "clearance delivery", depending) normally will coordinate putting your destination (for visual/VFR flight following) or full route (for IFR/instruemnt) into the ATC systems before you takeoff so that you can talk to the approach controllers once you leave and they can provide you traffic advisories, etc.

Or if your route allows, just not get flight following at all (and then ATC has no way to reach you). So SQL tower closing will also add to the workload for the SFO/OAK approach area.

My initial thought is no, there is too much complexity, but AI could help ease the load. I'm not really informed about air traffic systems, just curious.

Innate conservatism is what happens when deviations from perfection lead to collisions, and for the most part "AI" success remains a stochastic matter, gigabyte to terabyte sized tensors that are not human-intelligible. A black box which cannot be readily, safely validated in the real world.

                                                                                                                                                                                                                                                                          With that said - algorithmic, automated, and digital systems for collision avoidance at the very minimum have and could continue to make ATC jobs significantly easier. The radio voice channel is a particularly low fidelity, low bandwidth way to mete out information and directives.

Years ago a VA thoracic surgeon was trying to find someone to build them a tool to listen in an OR for surgeon commands and team member acks, and if it saw a command without an ack, to nudge. Context is surgeons are both team managers and individual specialists, and when heads down as specialist, the managerial role gets load shed. So a dropped command may not be caught before bad things happen. The VA does OR pickup teams, so there isn't the polished but idiosyncratic load sharing of long-standing teams. And the acks are more formal. He was fine with a high false negative rate (catching anything is good), and a moderate false positive (nudges are low cost). That seems now plausible. Aside from tech maturity, the biggest challenge then envisioned was willingness to be recorded. Though perhaps the real fix is staffing the team management role, but that was above his pay grade.

Everything happens too fast to insert a keyboard in the middle (*), and voice recognition would be too error prone for something safety critical.

The only busy airport doing this kind of thing is London City Airport, but that has 3M passengers a year and DCA has 25M. That was motivated by the lack of space at London City Airport, so they demolished the traditional tower to reallocate space.

I'm probably misremembering some details but there were battery-operated radios and little tablets being passed around with scribbled information.

                                                                                                                                                                                                                                                                                  • joezydeco 18 hours ago

But AI has been mentioned in the planning of the next generation of ATC.

Why not just regular software? Couldn't airplanes just send a message that they want to land and the Air Traffic Control software sees where they are and what other aircraft are around and sends everyone the appropriate messages?

                                                                                                                                                                                                                                                                                        The human ATC system is very good at handling exceptions, including various kinds of emergencies, pilot errors, and reasons to prioritize one plane over another. The human controllers also typically have a good understanding of the details of airspace, regulations, policies, aviation customs, and the capabilities of various kinds of aircraft.

                                                                                                                                                                                                                                                                                        So for example, a plane can have a "missed approach and go around" when trying to land. I was once on a plane that did that because of extremely high winds. In that case, the plane that was supposed to be on the ground is suddenly climbing again and is going to need to turn in order to repeat the approach.

                                                                                                                                                                                                                                                                                        A plane can have a medical emergency onboard, so it needs to land at an unexpected airport, possibly faster than a normal landing, or starting from a somewhat atypical position. I was once on a plane that did that because someone onboard had a seizure.

                                                                                                                                                                                                                                                                                        A plane can have damage or equipment failures that the pilots find it hard to assess directly, so it needs to fly around for a while to give the pilots time to "run checklists" or perform various tests, or sometimes to let a ground-based observer report on something about the plane (!), or just to develop their intuition about how functional the plane is. It might then need to land at an unintended airport or return unexpectedly to its takeoff airport. I was once on a plane that did that because of bird strikes during departure, where the plane was damaged but the pilots were unsure how seriously.

                                                                                                                                                                                                                                                                                        A pilot might misunderstand something or disobey regulations, and that pilot or another pilot might be told to take some unexpected evasive action to avoid a collision. (This is one area that has been productively automated in some cases via TCAS, where the aircraft themselves can sometimes figure out what an appropriate maneuver would be before a controller tells them one.) I haven't personally experienced that.

                                                                                                                                                                                                                                                                                        There might be another kind of emergency where a runway is closed and a large number of planes need to be diverted (like right after this collision where DCA was abruptly closed).

                                                                                                                                                                                                                                                                                        There might be negotiations with an uncooperative or mentally ill pilot (like the tragic story of Richard Russell in 2018, but also a number of incidents that had happier endings).

                                                                                                                                                                                                                                                                                        Pilots might also negotiate more cooperatively with ATC related to diversions and priority in situations like bad weather, where the airport has less capacity than originally expected and the pilots need to determine whether they will divert to a different airport. In this case the air traffic controllers may talk to different pilots about their fuel levels and other factors that make them better and worse candidates for changing flight plans. En-route (ARTCC/ACC) controllers will also negotiate with pilots about changing altitude to reduce or avoid turbulence.

                                                                                                                                                                                                                                                                                        There are occasionally cases where a pilot is incapacitated and someone with less training and experience needs to be advised remotely on how to land a plane. (This is mostly very small planes but ATC will still ultimately deal with these emergencies.) In that case other planes also need to be kept away from the incident aircraft and maybe diverted elsewhere.

                                                                                                                                                                                                                                                                                        Specifically for takeoff and landing, there are often multiple planes using the same runway (for takeoff, landing, or both) in relatively quick succession, or possibly using runways that cross each other. In this case, a controller needs to keep an eye on how quickly pilots have (or haven't) complied with specific clearances, e.g. to cross a runway on the ground, because the clearances may need to be revoked or modified if they aren't used quickly enough (because of the presence of other aircraft that have also received clearances that will soon start to conflict with the older clearances). This also includes checking whether planes that have landed have vacated the runway expeditiously (since if they haven't done so, for whatever reason, other planes may soon need to be told to go around).

                                                                                                                                                                                                                                                                                        There are also cases where military or law enforcement authorities may ask or demand to modify normal ATC procedures or clearances because of some special operation or problem. The simplest case is that they might ask to prioritize a government aircraft over civilian flights for some reason, or ask certain other operations to stop e.g. during a takeoff or landing of Air Force One. (I just watched this a few days ago with an Air Force One departure from Las Vegas, where other departures and landings were temporarily but briefly suspended. So that had to be planned and communicated to various pilots, some of whom then had follow-up questions about what they were or weren't allowed to do.)

                                                                                                                                                                                                                                                                                        Pilots are also considered to have ultimate responsibility for the safety of their flights and passengers, and they can also refuse some ATC instructions, or deviate from some normal procedures, in emergencies. So for example, a controller might believe it's safe to land in certain weather conditions and might give a pilot a certain clearance, but the pilot might not feel up to completing the landing and might then refuse to do so. The controller will have to understand the pilot's intentions as best as possible, and deal with the consequences of those intentions (e.g., once again, keeping other planes out of the way, or trying to find a new routing that the pilot will be willing to accept).

                                                                                                                                                                                                                                                                                        ATC is also responsible for passing some kinds of information to and from other parties, like in case of an emergency landing communicating with emergency responders so that they understand the nature of the emergency and whatever facts will help them respond more effectively. And they have to tell other ATC facilities about problems and situations that will affect them, like in-flight emergencies, closed airspace, closed runways, closed airport, etc.

The pilot could also be given a longer route than usual in order to have time to "work checklists" in preparation for the landing, or in order to burn off fuel so that the plane will weigh less (and be less likely to cause a huge fire) upon landing.

                                                                                                                                                                                                                                                                                        If some navigation equipment is broken, the ATC facility could help with navigation or with diagnosing the problem (by describing visual landmarks, or by estimating the plane's current speed and heading based on ATC radar).

As you probably know, crashing an aeroplane is not generally recommended. There are many factors that may contribute to a crash, such as weather, technical malfunction or human error. Appropriate training, regular maintenance and flight planning are some of the best practices which help minimise the likelihood of a crash. I recommend revisiting these factors. Is there anything else I can help you with today?

There were 3 aircraft involved. Game AI in the 1980s was good enough to handle the amount of "conflicting traffic" involved here. You're arguing in favor of automation, not against it.

No one hired last week would have been running things today (if they were hit with the freeze).

There's examples here of rescinded offers after doing irs on-boarding: https://www.journalofaccountancy.com/news/2025/jan/executive...

Then again, Musk denied the buyout will work this way, that agencies can just do whatever they want on this and OPM seems to agree, so who knows.

They basically move in one dimension. And the tracks can have (near) contact-based sensors along the way where the exact distance is known. (And in the US, there still is human conducting in a lot of the US)

Something like one flight declaring a mayday while another one just lost communication, all while the radar just started glitching in a weird way. Human intuition and common sense can sort it out. Deterministic algorithms would not.

On 9/11 ATC had to land almost 3000 planes in 1 hour. I'm not sure if that sort of national coordinated grounding is part of ATC training, but it's certainly not something I'd want to leave to some code that has never needed to run in production before.

                                                                                                                                                                                                                                                                                                                          It just seems like software could pretty easily compute non-intersecting flight paths for all planes and assign them accordingly. As well it could real time monitor all trajectories and continue to give out the updated flight paths. I don't see why you also couldn't run a trillion tests using real and simulated flight data to make sure it works well.

There are scenarios like runway closed and all traffic has to be diverted. Loss of communication. Various emergencies. Weather changes. It's not just a question of 3D motion planning. Controllers in the tower also use their eyes.

                                                                                                                                                                                                                                                                                                                            In your imaginary system how is the software "tower" communicating with airplanes, using voice? I don't think we even have software that can reliably decode the variety of human voices over radio that a controller can respond to.

                                                                                                                                                                                                                                                                                                                            One can imagine a digital protocol to all airplanes but technology works its way really slowly into aviation.

London Heathrow is widely regarded as the busiest two runway airport in the world. They allow less than 50 arrival per hour. Are there any airports in the world that can have "hundreds of arrivals per hour"? Conservatively, 200 can be considered "hundreds", then you would need 8x runways operating at max capacity. That seems hard to imagine. Google also tells me that Atlanta (normally the business airport in the US) can handle about 250 "operations" per hour, so let's say half for arrivals.

                                                                                                                                                                                                                                                                                                                              Serious question: Why is 3D such a hard problem for modern computers? I could imagine a plane enters a cylinder of airspace near the airport and automatically communicates by radio waves information about itself. Then, HAL9000 can provide guidance as a landing plan.

KATL has 2,100–2,700 arrivals and departures per day. Even if we assume those are equally spaced throughout the day (they aren’t) we’re over 100/hour.

                                                                                                                                                                                                                                                                                                                                But sure. It’s a mild exaggeration. It still doesn’t change the core point.

                                                                                                                                                                                                                                                                                                                                3D isn’t just “magically hard” for computers, but the process for routing traffic is wildly complex and a bunch of planes arriving and leaving at semi-random times, directions, and with different requirements and capabilities is where the problem starts not finishes.

                                                                                                                                                                                                                                                                                                                                The happy path is relatively easy. The exceptions are innumerable.

Like bird strikes, engine failures, trying to decide how to handle that. What is the loss function the AI is supposed to apply if an emergency landing is needed?

                                                                                                                                                                                                                                                                                                                                  And then if you have people flying the planes, you have to deal with people mostly _but not always_ doing the right thing. So now you build out a plan and have to deal with consequences of that.

                                                                                                                                                                                                                                                                                                                                  So at the end of the day you're still looking at funneling humans into a thing. At worst you could consider ATC as "customer support", there to press buttons on machines to actually handle a bunch of logistics because the pilots need to figure things out.

                                                                                                                                                                                                                                                                                                                                  On top of all of this, airports are trying to get through a lot of flights quickly. So people can make snap judgements about whether planes can or cannot advance, what they should do, etc. No matter how well your plan is, the instant a pilot mishears something it's over.

                                                                                                                                                                                                                                                                                                                                  If we can figure out self-driving cars, maybe we can talk about replacing pilots with AIs. But in the meantime there's somebody not following the plan often enough.

                                                                                                                                                                                                                                                                                                                                  This does lead to an interesting question for me, though: what is the biggest "human movement" system that is actually entirely hands-off logistics? I would imagine that postal service companies are doing a lot but every major person moving operation seems pretty hands-on from the outside.

Autopilots are a thing, and have been for decades. Modern airliners routinely land themselves, and Garmin have developed an emergency landing system for general aviation aircraft which can handle everything including selecting an airport and communicating with ATC in the case of the pilot being incapacitated.

                                                                                                                                                                                                                                                                                                                                    In many ways a self-piloting plane is an easier problem to solve than self-driving cars. Every plane has (or will have in the near future) a beacon on it transmitting it's location to every other plane around it to allow collision avoidance, and the procedure for getting from one major airport to another is pretty much prescribed in the form of standard departures, arrivals, and airways. The big difference of course is that if a car on the road breaks down and the AI can't handle it then the car can just stop, and baring someone not noticing and plowing into the back of them everyone will be fine, while if that happens in a plane it's a matter of time until the thing falls out of the sky killing everyone on board.

It's all of the management in the air and on the ground. Could a computer eventually do it autonomously? I would think eventually, but the problem is handling exceptions. The Navy has been experimenting for years with a digital replacement of their Ouija board analog flight deck management tool for carriers [1]. And even then, people are still making most of the decisions.

                                                                                                                                                                                                                                                                                                                                    And ATL is a crazy busy airport (there's an old doc on Netflix I think which is interesting). To confirm your question, ATL can run 5 runways nearly continuously[2]. It would be interesting to know what they peak at during a busy Monday morning, but my guess is they are more constrained by gate space at this point.

I could imagine a plane enters a cylinder of airspace near the airport and automatically communicates by radio waves information about itself. Then, HAL9000 can provide guidance as a landing plan.

Maybe it is a more modern phenomena, enabled by a steady diet of 30 second videos.

                                                                                                                                                                                                                                                                                                                                        I don't even know where to begin trying to interlocute when the starting premise is "3D is hard for modern computers."

                                                                                                                                                                                                                                                                                                                                        So I speak straightforwardly, in a way that I wish wouldn't be seen as rude, but it is.

                                                                                                                                                                                                                                                                                                                                        So it goes.

                                                                                                                                                                                                                                                                                                                                                  - The first comment was objectively, straightforwardly, dismissive. You questioned one statistic, then ignored the thrust of the comment and the comments leading up to it, instead framing the difficulty as "modern computers have a hard time with 3D", eliding the main point communicated.

                                                                                                                                                                                                                                                                                                                                                  - You then replied to my comment to tell me I'm wrong, it wasn't dismissive. This is also, in itself, dismissive. I had already fisked you, and I felt bad, so I didn't want to get overly literal and criticize you roughly again, in front of a crowd, so soon. So, I choose to keep it brief, rely on your ability to recognize the irony in your reply being dismissive in telling me the original comment wasn't dismissive, especially when combined with the wink.

                                                                                                                                                                                                                                                                                                                                                  To be hyper clear, it's...unusual...when communicating with others to ignore most of what they just said and fixate on one illustrative part of what they said, then when told you were being dismissive, to just say "I wasn't being dismissive" and put the burden on the listener. It's so unusual as to be objectively amusing.

                                                                                                                                                                                                                                                                                                                                                  You certainly did not mean to be dismissive, but you were. I sympathize with the reflex, I am 100% sure I've made many similar errors in my own journey, probably more than you ever have and will. It is a problem area for me.

                                                                                                                                                                                                                                                                                                                                                  With humility, I'd humbly suggest that when given feedback, rather than briefly asserting the feedback is incorrect, you come with curiosity and ask why it came off that way.

                                                                                                                                                                                                                                                                                                                                                  Given their answer, you'll be able to tell very quickly if the person is having a bad day/picking on you, or if you were unclear.

                                                                                                                                                                                                                                                                                                                                                    Your advice would make sense if I was the same person, but if I was the same person I would have responded very differently to the criticism. I gave a brief reply because I'm a third party.

A metro track can have a train every 60s.

From a small set of input parameters the algorithms generate the ground track, altitude profile, and speed profile required to implement an experimental 4-D guidance system. Given a sequence of waypoints that define a nominal flight path, the first algorithm generates a realistic, flyable ground track consisting of a sequence of straight line segments and circular arcs. Each circular turn is constrained by the minimum turning radius of the aircraft. The ground track and the specified waypoint altitudes are used as inputs to the second algorithm which generates the altitude profile. The altitude profile consists of piecewise constant flight path angle segments, each segment lying within specified upper and lower bounds. The third algorithm generates a feasible speed profile subject to constraints on the rate of change in speed, permissible speed ranges, and effects of wind. Flight path parameters are then combined into a chronological sequence to form the 4-D guidance vectors. These vectors can be used to drive the autopilot/autothrottle of the aircraft so that a 4-D flight path could be tracked completely automatically; or these vectors may be used to drive the flight director and other cockpit displays, thereby enabling the pilot to track a 4-D flight path manually.

This means that any delay is in fact a distortion of the trajectory as much as a level change or a change of the horizontal position. Tactical interventions by air traffic controllers rarely take into account the effect on the trajectory as a whole due to the relatively short look-ahead time (in the order of 20 minutes or so).

When you talk to ATC you always need your tail number and airplane model. Why? Because a landing Cessna 150 is moving at 70mph. An incoming jet is moving at 130mph. And the jet can’t just slow down to 70 or it will fall out of the sky. They need to consider aircraft performance in all aspects of planning.

You pretty much just have either land ASAP or circle to burn fuel and then land.

Trains have a single axis of movement that sometimes cross or combines with others. Aircraft have three axes of movement all under human control.

I'd want some highly skilled humans there monitoring things but, yes. The air traffic control system of the US is absolutely incredibly amazing, but their entire mission, technology and equipment used to accomplish that mission, etc need to be reviewed, maybe rebuilt to be even safer.

Obama promised to change this stuff, and he couldn’t do it, because he innately trusted the same people who made the mistakes to “study” how to fix them.

The consent to an American King is being manufactured in front of our very eyes.

This is only a few days after a change of administration along with sweeping government changes. Don't you think it's worth asking questions a little more deeply than this?

Not to mention the amount of training and effort needed to become one in the first place with basically zero job security or recourse if you make the wrong person angry.

I think this is going to be a very big deal and very quickly become a political football. Regardless, this is absolutely awful and extremely unfortunate.

                                                                                                                                                                                                                                                                                                                                                                                          This is an often repeated misconception. ATP always needed 1500 hours. What wasn’t required is for both pilots to have an ATP, just the captain - the flight officer only needed a commercial certificate. Airlines would hire with lower hours and train on the job.

                                                                                                                                                                                                                                                                                                                                                                                          While both pilots in the crash did have over 1500 hours, the flight officer did not in fact hold an ATP. The rule also changed some of the ATP training requirements, and there were other regulation changes on duty cycles, etc.

                                                                                                                                                                                                                                                                                                                                                                                          It’s very possible we’ve had a run of good luck since 2009. It’s also possible some of the rule changes helped. I wouldn’t dismiss that possibility too quickly.

Fox News would be going off 24/7 about "DEI" or some such for weeks on end. That strategy seems to be successful, so I would expect the other side to start employing it more as well.

And it's not indicative of a junior or unqualified pilot (doesn't rule it out, just can't infer much from the phrase in this context).

                                                                                                                                                                                                                                                                                                                                                                                                                                    At the extreme, fighter pilots fly almost exclusively training flights because we're not actively waging war at the moment.

And lots of shuttling of DoD and other government VIPs from location to location across the DC metro area.

That unit's [1] task is to provide transportation to senior government officials and security forces around the capital, including to and from that airport. If they didn't train to operate there, then their first time doing so would be with someone like the Secretary of Defense onboard or during some other mission that's critical to national security.

It's been wild having the house shaken at noon or 1:00 from pairs of fighter jets!

I'm normally up there once or twice a week and usually there's nothing like this.

Isn’t it designed for such situations where 2 aircrafts collide? Do military crafts not have it or something?

In dense airspaces, those alerts tend to trigger frequently, so there’s a strong chance they may have dismissed it. The CRJ crew might have been aware of the Blackhawk’s presence, but if the other crew had visual contact with the approaching traffic (the CRJ), they might not have felt the need to take further action.

But...why doesn't TCAS show the pilots at least as much information as I would have seen on my phone if I'd been browsing flightradar at the time? It's one thing to design a system with "don't saturate the operator with audible alerts" but another to say that it's appropriate to withhold very valuable information from the operator ("there are loads of planes in the general vicinity, but yeah look at that one coming at you from the left").

The videos of the crash that I can find on X just show a small airline light suddenly turning into a low-res explosion. (Edit: ah. yes.)

The helo must have gotten in the way (as opposed to catching up from behind). The airliner's lights are unmistakable, so how did the helo pilot not notice them? The airliner's pilots might not have had a chance to notice the helo. Since the helo was crossing an active runway approach the fault has to be with them.

They're only noticeable if they're pointed towards you (but then they're very bright). They were visible to the camera but perhaps not to the heli.

At night, if you expect it to be a big jet and it looks small, you presume it's just further away. I think they saw it, saw it small and presumed they had enough time to make it in front of it.

Lots of commuter flights to NYC, Boston, etc.

And imagine how exhausting it is for debunkers, when they try to say "you're hallucinating", the conspiracy theorist holds strong to his belief, thinking the debunker doesn't get it or they're part of the lying pack.

You experience the thrill of discovery, the excitement of finding the rabbit hole and tumbling down it. Because you were persuaded to “connect the dots yourself,” you can see the absolute logic of it, even if you made it up.

(Tail number PAT25). FlightAware doesn't show it but it might have been tracked by open source ADS-B receivers.

US military aircraft don't have FAA "N" registration numbers like civilian aircraft do. Military aircraft do have official numbers but those aren't used for ATC or radio communications.

In other words, it was a VIP transport flight (there may not have been any VIPs actually on board at the time).

DCA has been a high-risk airport really since the jet-age, and I have a feeling this might be the end of it as a major passenger airport (at least for Part 121 operations). DOT/FAA are really going to need to step up after this and figure it out, for good. I hope there are survivors but it is really cold in that water right now, look up Air Florida flight 90 for a completely different accident, but in a similar time of the year.

The traffic at DCA only keeps going up, and I've heard chatter that it's because a lot of congressman and senators prefer taking flights from DCA instead of driving to Dulles or BWI.

First, we should fill the currently vacant US Secretary of Transportation role. Then we should fill the currently vacant FAA Administrator role. Then we should fill the FAA Deputy Administrator role [0]. Then we should fill the currently vacant DoT Inspector General role that Trump just opened up by illegally firing this watchdog without the required 30 days notice to Congress [1]. Then we can start investigating.

I'd certainly never have flown on a plane into DCA if I had known that military helicopters were routinely buzzing around in the same airspace with no technological deconfliction aids.

Trump is out there blaming Biden's administration for hiring bad ATC under the banner of DEI. Meanwhile, his detractors blame him and Musk for letting go of some FAA administrator.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                              But of couse neither of those explanations are likely to hold water. The sad, mundane reality is these people probably lost their lives due to a miscommunication or misunderstanding between ATC and the helicopter pilots. And this political mudslinging will probably get in the way of us ever implementing process changes so it doesn't happen again.

That unit's [1] task is to provide transportation to senior government officials and security forces around the capital, including to and from that airport. If they didn't train to operate there, then their first time doing so would be with someone like the Secretary of Defense onboard or during some other mission that's critical to national security.

                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              "Training" here also doesn't imply some 21 year-old flight school student learning to fly. The aviators assigned to that unit are typically more senior people who've already done a tour or two with more conventional units.

Its very cold in DC right now and an airplane crashing is much more catastrophic.

But why don't ATC / FAA stratify aircraft type and use by altitude. Like all commercial traffic is put in even thousands altitudes. And the Military / EMS gets the odd thousands.

From the crash it seemed like the helicopter pilot wasn't strictly following the ceiling.

If you mix in helicopter traffic that needs to run at lower altitudes anyway, that is also near an airport, it becomes a much more difficult scenario to control.

Planes landing have to traverse through 200ft. Therefore vertical separation impossible.
