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.
lawlessone
I think the crash was at 8:22 or 8:21, you can hear sudden commotion at that time.
wyldfire
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"
unsnap_biceps
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.
dylan604
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.
TylerE
There was a second American Airlirns flight only a couple miles and a thousand feet higher in altitude in the same approach course. You can actually see it in the video that’s circulating.
mlyle
It's pretty dang easy to misjudge distances and closing rates in a plane or helicopter, especially at night.
ketanmaheshwari
Is this true for the trained pilots as well?
throwaheyy
No, that aircraft (having taken off from Reagan, visible in the full not-cropped videos) is close to the Kennedy Center camera but is nowhere near where the CRJ and helicopter were.
trhway
> easier to see.
One has radars even on recreational boats. That was a military helicopter. At night. It would be hard to believe that it doesn't have nor radar nor IR cameras, and the plane would be lightened up like X-mas tree in both.
jahewson
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.
t0mas88
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.
I have no extra information on this incident so this is only generic input.

It wasn't a police chopper, it was a military VH-60, also known as a "White Hawk" [1]. It's a VIP transport helicopter, the same type that is used to transport the president.
~The flight track of the helicopter [2] starts at a property in McLean, VA (edited to remove likely inaccurate info)~
The chopper was based out of Fort Belvoir, and based on similar past flight tracks, looks like it probably took off from there too. CNN is reporting that there were 3 soldiers onboard, and no VIPs.

> The flight track of the helicopter starts at a property in McLean, VA
that's almost certainly not where the flight started, due to intricacies of how this sort of flight tracking works.
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.

And just to be clear, the POTUS/super-special VIP transport is run by the USMC out of Quantico[1], a bit further to the south along the Potomac. Belvoir is US Army, and does have VIP heelicopters (obviously), but it's not the same group that lands at the White House.
1 - https://en.wikipedia.org/wiki/HMX-1 They have some Ospreys and other things as well, but HMX-1 is the most famous and recognizable.
reaperman
[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.
twoparachute45
I didn't say it took off from the old embassy. 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....
dboreham
That house doesn't seem to have enough clearance vs the trees to land a helo. Note that Langley (CIA) is nearby.

Note that that track is not ADS-B at all. It’s triangulated from mode S pings (“MLAT”, https://www.flightaware.com/adsb/mlat/). I don’t know how accurate these are.

CNN is reporting the helicopter came from Fort Belvoir.
https://www.cnn.com/us/live-news/plane-crash-dca-potomac-was...
reaperman
The helicopter seems like it is typically stationed at Fort Belvoir. Does "out of Fort Belvoir, Virginia" strictly mean that the helicopter's flight started at Fort Belvoir, or that the helicopter itself is considered to be "out of Fort Belvoir" in a similar manner that LeBron James could be said to be "out of Akron, OH"?

i_am_proteus
The current embassy is indeed in DC proper, but it isn't directly across the river from DCA.
It's about a mile upriver, near the Watergate.
highcountess
Military flights do not fly ADB hot outside of the DC FRZ. It was also clearly exactly following flight route 4.
There are a few locations in that area it could have been coming from. Anything else would have made no sense flying through the FRZ from/to Belvoir.
reaperman
What is "flight route 4"?
highcountess
That was clearly a training flight

But does that provide any context? Military pilots perform training flights regularly - it's not necessarily indicative of an inexperienced pilot.

BBC is reporting that the Army has confirmed that it was a UH-60, not a VH-60, ie: not a VIP transport: https://www.bbc.com/news/live/cy7kxx74yxlt?post=asset%3A62b9...
Although it's early on and these communications are often chaotic/inaccurate.
twoparachute45
I thought it was a VH-60 given that it was callsign PAT25 (PAT is Priority Air Transport and they use the VH-60 for those flights), but if this was a training flight, they may have still used the PAT callsign while flying a UH-60.
alistairSH
Both are "Black Hawk" airframes, right? The VH-60 variant is just a UH-60 that was build/configured for VIP transport vs the normal UH-60 utility variant.
IE, other than paint, they look the same to a casual observer.

I'm impressed by your, and their, hearing comprehension here! Granted, English isn't my native language but even with concentration I struggle to hear what they say.
vharuck
It's easy to forget how many skills and "heuristics" go into listening. 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.
bolognafairy
Previous experience with aviation radio comms helps a lot. Typical radio comms essentially follow a template, and it’s done in a way where you can safely approximate a LOT (…just not numbers). But the…phraseology if you will, can be approximated quite easily with experience.
Funnily enough, American ATC / pilots are, I find, a lot more frequently ‘fast and loose’ compared to other areas, even English-speaking ones. Countless recordings online of EALD pilots being befuddled by some self-identified hotshot air traffic controller using overly casual / sloppy language, sometimes resulting in near misses or worse.

Any takeaways from this? ATC not responding with separation but Blackhawk continuing anyway?

Obviously it will take some time for the full accident analysis but there have been quite a few near misses lately due to air traffic controller errors. 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.
NaOH
Hiring controllers is not easy. 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.

That's shocking and disturbing, and is pretty much a textbook example of exactly the type of thing opponents to DEI have been referring to for how DEI and Affirmative Action result in a lowering of the bar. 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).

It's kind of odd that blog post doesn't mention that the biographical assessment it's talking about was only used between 2014 and 2018.

I thought Trump instantly blaming DEI was ridiculous in this case but I’m somewhat reconsidering.

Another problem is the maximum entry age for the ATC school - if you are over the age of 31 you can't apply.

This is, justifiably, very similar to nuclear reactor operators. Pay needs to reflect the working conditions to attract more people (it does for reactor operators).
insane_dreamer
> appropriate degree
what's considered an appropriate degree for ATC?
nradov
No college degree is officially required. Candidates with aviation related degrees probably have a better chance of making it through. But there are plenty of working controllers who have only a high school diploma or learned the job as enlisted military personnel.
"Have either one year of general work experience or four years of education leading to a bachelor’s degree, or a combination of both"
NaOH
In her case it was a Bachelors in Aviation and Aerospace Science with an Air Traffic Control Concentration. There may be other programs or concentrations which are acceptable.

In addition, ATC is not allowed to go on strike, limiting the degree to which they can bargain for better working conditions, pay, etc.

Meanwhile, San Carlos Airport (KSQL, near San Francisco) is going ATC-zero on February 1st. The tower will be unstaffed.
https://content.govdelivery.com/accounts/CASMATEO/bulletins/...
"The FAA has awarded a new contract for air traffic services at SQL to Robinson Aviation (RVA). 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"
why_at
I've been working towards my private pilot license at San Carlos and I don't know what's going to happen if they can't find someone to do this job. The airport can get very busy sometimes and it seems like it could be dangerous to have nobody working the tower.
I sympathize with the ATC workers though. It's ridiculous that they can't pay them a decent wage for the area, there's only two of them as far as I know.
ryandrake
The SQL tower service provided by SERCO already had a poor recent reputation among Bay Area small aircraft pilots, with controller(s) who are obviously overworked/underpaid. 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.
dylan604
> The tower will be unstaffed.
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.
cco
Surely the FAA would just shut the airport down in that eventuality, no?
Seems tenable for a GA airport in rural Wyoming but that is far too close to a major hub.
jonathanlb
Honest question: are air traffic controllers at risk for being replaced with AI systems? 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.

In fairness to the current administration, while the hiring freeze may have impacted ATC hiring, that is not causal here. No one hired last week would have been running things today (if they were hit with the freeze).

Someone that was hired weeks or months ago, but scheduled to start last week, could* have been included in the hiring freeze.

elicash
They were replying to a comment that said "We're going to need to hire more controllers."
So I took their comment to be forward-looking.
It's worth adding that Elon Musk's email that had the supposed "buyout" went to ATC folks -- however management was telling them they'd need to work through their resignation date, regardless, removing the point of it. 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.

Is there an actual reason why the control tower work can't be fully automated? For train control lights we almost don't rely on human operators anywhere.
LeafItAlone
> For train control lights we almost don't rely on human operators anywhere.
Trains are on tracks. 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)
That’s a very different problem space than the three dimension, unattached, space that air traffic moves in.
SeptiumMMX
Because things can go from routine to multiple simultaneous life-threatening failures very quickly. 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.
randerson
The problem space is too broad.
E.g. 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.
stouset
Trains run on fixed tracks with fixed intersections, and one track might see a handful of them per day.
Planes around airports come in from all directions in three dimensions, and there can be hundreds of arrivals per hour.
These are vastly different scales of problem domain.
namirez
How would you deal with all sorts of emergencies involving human pilots? For unmanned aircraft(aka drones) it’s a lot easier to implement unmanned traffic management (UTM).
thowawatp302
Weather. How often do weather events change the entire traffic flow into a train station?
I’ve heard ATC swap landing and takeoff directions in the space of 10 minutes because of weather
justinspace
I mean this sincerely. What is more likely: that we've spent several decades ignoring very real automation solutions to this problem, or that it's a really, really hard problem that could get people killed?
foobarchu
Not an expert but I can't imagine that would go very well. Trains have a single axis of movement that sometimes cross or combines with others. Aircraft have three axes of movement all under human control.
rsanek
Wow, a controller can be hired and on the job in less than a week?

To quote the order itself:

ATC surely falls under public safety. Additionally, the ATC issues stretch well back into the Biden term, and you can find plenty of articles discussing the controversy elsewhere.

I believe this happened in DC SFRA, which is a 30-mile radius specially controlled airspace due to the level of traffic and national security interests.

And we also did make it basically impossible for ATC workers to strike, so its not like the ATC workers could have said "fix this shit so people don't die or we will strike" because they can't really and anyone who says it anyways alone is going to be given the boot and blacklisted from the job. 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.

If you listen to the ATC recording, around 15:50, they instruct the helicopter to watch for traffic, specifically this flight, and clears them for virtual separation.
It's the helo's fault. They likely misjudged the plane due to assuming it was a large jet but it was a regional jet, so it was way closer than they thought it was.
It's a tragedy, but I don't see how it would be ATC's fault. But that's just my 2 cents.
jonlong
> They likely misjudged the plane due to assuming it was a large jet but it was a regional jet
Maybe this is possible, but it seems implausible given that ATC explicitly refers to the jet as a "CRJ".
JADev62096
It could be that the right call was for ATC to deny the request for visual separation and for them to do the deconflicting themselves. Not saying that's the case, I don't know, but that's one way it could be (partially) ATC's fault.
thallada
Do you have a link to the recording?
anigbrowl
That's the best theory I've seen so far, but it's still really really bad.
YZF
It's way to early to say but one of the threads seemed to indicate the helicopter pilot was told about the airplane and instructed to maintain visual separation. I used to be a military air traffic controller and that was fairly common practice but I wasn't aware this is something that happens in civil aviation where usually the margins should be much higher.
Crazy and sad. I guess we'll learn more over the next few days. Going into the water is maybe better than crashing on land. Hopefully some people make it.
EDIT: Found this: https://www.faa.gov/air_traffic/publications/atpubs/atc_html...
nradov
It's very common for civilian ATC to instruct pilots to maintain visual separation, especially when they're both in the approach pattern. For airliners, TCAS gives an extra level of safety to guard against pilot errors. But I think many military aircraft lack TCAS.
dralley
It is so incredibly tiring that you dweebs try to blame every single bad outcome in the world on cough minorities cough "DEI", with zero evidence.
In fact, literally when you posted this comment there were already ATC recordings floating around of the controller telling the helicopter pilot to maintain separation from the exact airliner they crashed into.
Take a look in the mirror.

userbinator
At least DEI can't be blamed for much longer.
bryant
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.
https://www.flightaware.com/live/flight/AAL5342
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.

Regulations are written in blood, which is why it's such a disservice to indiscriminately tear it all down. We will re-learn the same lessons and people will pay for those lessons with their lives.
derektank
Some regulations are written and blood but some regulations are written to cover someone's ass and the two should not be treated equally. 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.

Why don’t you identify all these easily found regulations then?
There’s a whole YIMBY movement, for example, that has identified specific regulations that are no longer valid and have made tremendous strides in proving and changing these regulations for almost universally better outcomes.
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.

FAA is however an agency that regularly tangles with SpaceX and could be seen as slowing them down. Seems like a conflict of interest for the guy tasked with government efficiency.
unsnap_biceps
That's entirely true. Thank you for the correction. I spoke overly broadly.
rayiner
If everyone writing regulations were as rigorous as the FAA people wouldn’t be clamoring to reduce regulations.

The latter is how you get a workforce qualified to write the former, rather than a bunch of hacks who know nothing about aviation safety.

And which regulation was eliminated that caused this?
coddingtonbear
This would, if the system is working, be the blood that future regulations are written in. That these kinds of things happen so rarely came to us at a cost of past lives.
UniverseHacker
I have a feeling from your comment that you know more about aviation than you are letting on, and the part about being in DC not giving you a right to an opinion seems pretty silly in that context.

blancolirio (active pilot who regularly makes videos about crahses with the aim of improving safety) just released a new video on this accident: https://youtu.be/_3gD_lnBNu0
Summary: The helicopter might have been a little bit too high. The night vision goggles might have negatively affected the vision. The two aircraft were probably on different frequencies so didn’t hear each other. And the helicopter might have focused on the wrong plane to avoid because they didn’t see the right one thanks to the city skyline. It looks like the classic swiss cheese where multiple problems stacked up to cause the collision. See the video for details.
Aeolun
Wouldn’t the aircraft see the helicopter?
gomijacogeo
Unlikely; the pilots are (correctly) following the approach controller's direction. It's approach's responsibility to keep them clear of other traffic. Also they just got handed a different runway to land on that's a lot shorter and in one of the more complex airspaces of the planet; they're busy.
datavirtue
Air traffic controllers are staffed at 65% across the US. Budget cuts and turnover are cited. Meanwhile the FAA is being rattled to its core by the Orange One.

This seems to be a resolved problem and one that we shouldn't have in this era. An unnecessary tragedy.

DCA is open to the public.
bsder
DCA is open to the public. But it has lots of ways for Congressmen to avoid the inconveniences that you and I have to endure.
The other airports in the area do not have those.
rayiner
Not disagreeing, but is there something particularly wrong with DCA?
jonstewart
DCA is great to fly in and out of (I live in DC proper), as it's close, isn't hard to get to, and has a Metro (our subway) station right in front of the terminal, and the airport is fairly easy to navigate once you're in. 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.
tssva
DCA is just across the Potomac River from DC and thus large amounts of restricted air space. 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.
cyberax
It's in the middle of a city, with lots of restricted airspace just _seconds_ of flight time from it.
jcranmer
From what I've heard, it's a challenging airport to land at, particularly because one of the approaches has two sharp turns in it, and I think the main winds tend to be annoying crosswinds for the main runway. Also, the airport is surrounded by lots of restricted airspace because, you know, seat of federal government and all that.

I sometimes wonder about the value of these news stories on forums and social media.
It's all pretty much wild speculation with several potential causes already mentioned on this forum.
News important yes, every rando with a few shreds of factoids speculating, not so much.
throwaway2037
Anything about civilian air safety is like catnip for nerds. It is the ultimate armchair nerd sport -- speculating about reasons for a civilian air crash. I guess this discussion will be more than 1,000 comments before its heat-death.
francisofascii
Here we get air traffic controller recordings, and people who are ammeter pilots. It is more informed speculation than my "normal" friends or co-workers.
duxup
I suspect moderately informed, but not completely informed, is the worst kind of speculation. It has a sense of authority and knowledge that is hard to pinpoint its accuracy.
Almost all the amateur theories in here, just by the variety, are going to be dead wrong.
whateveracct
It just sounds more informed. Just like all the "amateur" physicists who speculate on theoretical physics posts on HN.

I’ve been saying something similar to friends recently. We have access to a bit Too much news for our own good.

Here, I get ATC transcripts and learn about the helicopter flight paths. Traditional news describes an airliner with 60 people on board as a “small plane.”

In this case there is no or negative value. Wait for the facts, avoid the noise and wild speculation.

Well, last night when there were only 10 comments here, the essentials of what had happened were available from those comments. Meanwhile the mainstream news TV I was watching at the same time was presenting either zero information, or false information (e.g. that 4 survivors had been rescued).

Arguably we have that with the current US executive branch.

Yes, tons of speculation, and very little clear basic facts.
When I clicked, I expected to find the comments interesting (since I worked in a small corner of flight safety), but, skimming through, I kept feeling aversion to threads.
Most modern news organizations aren't much better.

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.
[1] When flights are approaching from the north, the main runway requires a pretty sharp right turn seconds before touching down. Approaches to the diagonal runway from the north take planes almost directly over the Pentagon.
Molitor5901
The press conference this morning mentioned that this was a new flight path. I wonder if the helicopter crew were not fully briefed on the new path, if that is the case.
GlenTheMachine
I work at NRL, east of DCA and about 500 yards south of the crash. 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.
dboreham
What it means is that the aircraft was on approach into runway 1 (ILS) and then on ATC instruction changed runway to 33 (no ILS). 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.
rtkwe
It wasn't a surprise, the ATC recording is out there already [0], also while it's a less common approach path it's not exactly new or that unusual military traffic has to deal with the commercial traffic all the time in that area.
[0] Crash happens around 8:21 the chopper pilot is advised of and reports traffic in sight at around 7:06 and 8:12 https://archives.broadcastify.com/44114/20250129/20250129200...
francisofascii
In looking at the radar recording, the plane appears to be approaching from the south going north (very slightly east), than diverts northwest to land on the runway, as you describe.
jauntywundrkind
Anecdotally, the amount of helicopter & air traffic going on around DC has been absurd this month.
My house in DC has calmed down some but we had a bunch of low flying fighters jets & helicopters for a bit. It's been wild having the house shaken at noon or 1:00 from pairs of fighter jets!
I've had an in-week around Tysons this week, and it's been wild seeing pair after pair after pair of helicopter flying east towards the city this week. I'm normally up there once or twice a week and usually there's nothing like this.
zzleeper
Agreed. Why so many heli's to McClean? Are they just too stingy to pay the I66 toll in the afternoon?
GlenTheMachine
I work at a Navy installation on the Potomac just south of DCA. 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.

This will be the worst disaster since Colgan in 2009 which is the crash that upped the hours requirement for ATP pilots from 250 to 1500 even though both pilots had over 1500 hours. 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.
lovecg
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.

Early indications are that the airliner and ATC were operating as planned, and the immediate cause of the crash was the military helicopter.

Damn. We’ve avoided a US airliner having a fatal crash since 2009.

It's a crazy accomplishment really, unimaginable how safe US commercial airplanes have been in the last two decades

As someone working in aviation safety, this is heartbreaking and awful to watch. The efforts of CAST and ASIAS in reducing aviation safety accidents have been very successful, but of course we still have so much to do.

There have been incidents that were just saved by luck (eg losing door in flight). And Too many near misses.

Better a near miss than a catastrophic incident.

Although Air Canada Flight 759 was far too close for comfort and should be classified as a failure of the system, even if it did not result in an accident.
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.
