The article claims the helicopter was higher than it should have been, but isn't it safer to fly high across the airport if you're crossing?
> "The helicopter was part of the Continuity of Government Plan, with the flight being a routine re-training of aircrew in night flight along the corridor."
Continuity of Government Plans is what they do when nukes get launched or a 9/11 sort of thing happens.
That seems like a misalignment of incentives.
They need to have as much skin in the game as everyone else.
The point is that for deterrence to work, it has to be credible. If Russia thought it could “kill” the US government so that no one would be able to effectively order a counterattack (either because they are dead or because they can’t communicate orders to actual nuclear forces), would they do it?
A disaster waiting to happen in retrospect. Similar issues at other airports like runway incursions, especially at crowded small airports like SFO and LaGuardia with antiquated runway layouts.
Sad to say, as a former aviator, I have seen it before where people died and families lost loved ones ultimately because of a systematic risk inherent in what they were doing, but also other times because someone flat-out just screwed up.
data recently analyzed by the board revealed that National Airport was the site of at least one near collision between an airplane and a helicopter each month from 2011 to 2024
I would say that statistic in and of itself qualifies as a "disaster waiting to happen". I agree that we should wait for the full report, but I don't think the GP is using hyperbole in this case.
Unfortunately, they don't always succeed. Every crash is a lesson learned too late. We endeavor to learn earlier than that, and when we don't, we make sure we learn in the aftermath.
Yes. The info still isn't that good.
That said, allowing helicopter operations underneath a final approach path is iffy. Ops.group has a discussion.[1]
You don't see aircraft at night, you see lights. And they're over a city--a gazillion lights. Thus all you really see are moving lights. But if two objects are on a steady collision path neither moves relative to the other. Thus both sets of pilots would simply have seen stationary lights, invisible against a sea of stationary lights.
Just as an example, look at a map and take note of where DCA is, where the Marine One hangar is, and where the White House is. All of this stuff is right around the airport.
Now, this particular flight wasn't landing there, but I don't think it is in any way confusing as to why military helicopters are in this area or taking these routes.
This is inherently very complicated and high volume airspace, and there is a lot of helicopters because there are important leaders who use military helicopter transport, not commercial airports, but many of the places they might be landing are all around DCA.
Three are occasional news articles and sci-fi worlds advocating for flying cars to replace normal cars. I imagine that would actually be like this situation but a gazillion times worse, rather than the promised elimination of traffic jams.
Not only does Reagan have the same design problem as LGA and SFO (built before jetliners, runways too short), it’s incredibly close to restricted airspace. No civilian needs to fly into an airport that close to DC.
Travel in/out of IAD from DC can take an hour, which is obviously why people there prefer DCA. And the flights there are all short-haul anyway, so many are the types of flights people are doing on short turnarounds.
The pain could be mitigated somewhat by adding seating areas and more aircraft parking while using larger planes. For instance, fewer flights total, consisting of 737s and a320s and eliminating flights that previously used shorter commuter sized aircraft.
Immediately after 9-11, lots of people talked seriously about whether to re-open it. Ultimately they did, because Congress wants it.
At some point, it's like saying "isn't it 'safer' not to take the freeway because everyone drives so fast?"
Politicians wanting contradictory things, oops.
1: You don't want to do that for the first time in wartime.
2: In case you've been living under a rock, we are at war with Russia right now. We just haven't declared war.

What's the next conspiracy? They have anti air weapons in embassies and wait for a military helicopter transporting a high value target?
Either way it's not worth 64 lives...
This mindset isn't conspiracy and framing it as such makes you sound like you have no idea what you're talking about.
> They have anti air weapons in embassies?
It'd honestly be pretty surprising if they didn't, but this is also why when countries officially go to war with each other the embassies are typically evacuated and/or evicted.
> Either way it's not worth 64 lives
Not a single person here or elsewhere is claiming otherwise.
I agree with you that it seems relatively unlikely that there would be a large weapons cache inside an embassy. I want you to consider the opposite scenario of what you're dismissing though.
If an American CIA officer in Russia wanted to shoot down a helicoper, do you think it would be that difficult for them to get ahold of a rocket launcher and do so?
After this unlikely series of events, what is achieved? Do American people give up because someone killed an easily replaceable politician with bad approval rating?
There's ADS-B receivers the size of a USB stick - because some are USB sticks and available for 50 bucks on Amazon.
Passive RADAR is an incredibly cool technology. Instead of the RADAR station transmitting its own signals, it relies on nearby high-power cultural transmissions (FM radio, broadcast TV, etc) as the signal source and measures the reflections of those signals off of aircraft. Since the majority of traffic in the region would be broadcasting ADSB, you'd be able to figure out which tracks from your Passive RADAR system correspond to aircraft without ADSB.
Especially in this era when this administration seems to be gearing up for military action in domestic spaces when Congress has declared no war.
Then we're not at war. Hope this clears things up for you!
There's no ambiguity here.
Regardless, 91.119 applies (harshly, and unambiguously, in some cases) to significantly safer operations than 75 ft visual separation from passenger aircraft in bravo airspace. That is absurd. Failure was built into the design from the beginning.
Yes indeed, failure was built in to the airspace design.
Turning ADS-B on/off likely has zero effect on the training/fighting relationship.
> But the Black Hawk did not operate with the technology because of the confidentiality of the mission for which the crew was practicing. That is because ADS-B Out positions can be obtained by anyone with an internet connection, making the system a potential risk to national security.
Seems like leaving it in listen-only mode would be wise, though.
On the other hand, I've got an internet rando who once told me to Google up MGTOW saying "I'm told".
Which one would you find credible?
Here's a map of the helicopter routes in the area. In this case, they were flying on route 4... https://www.loc.gov/resource/g3851p.ct004873/?r=0.67,0.258,0...
Yes, this group transports VIPs and sometimes does so in secret. This training flight was a "simple" check-ride for the pilot (simple in scare quotes because part of the ride was using the NVGs, which strikes me as fairly ridiculous in the DCA air space).
When this specific helicopter/mission joins the route, how fast it goes, what callsign it uses, when it leaves the route, etc. may not be so public. Or at least be treated as "try not to make it unnecessarily public".
Overclassification is absolutely a thing, too. I recall when the Snowden NSA leaks came out, government employees were still forbidden from reading the documents, even if they were published in the newspapers. Pointless? Yes. But those were the rules.
training on a confidential mission is just inviting disaster
Competent people still make mistakes. I wouldn't want to be anywhere near DCA airspace, personally.
Not just government employees. I was at a defense contractor at the time, and we were also instructed to not read any of the documents online, even for people who were technically cleared to read them through proper channels.
Edit: misremembering, wasn't the Snowden leaks, it was some earlier set of leaks on WikiLeaks

My dad's little four seat hobby plane has both In/Out. You can track him on FlightAware as a result, because it's continually broadcasting its location; it's certainly not rare or sophisticated equipment.

> The Army Black Hawk helicopter crew involved in the midair collision with an American Eagle CRJ700 last January at Reagan National Airport had turned off ADS-B because they were practicing a classified flight profile, according to a New York Times investigation.
I have been running an ADS-B receiver at home for 6 years via PiAware along with an AIS receiver. So yes, low cost :)

> A majority of respondents had used ADS-B In, with 56% of respondents reported having experience with either an installed or portable system. Of the group who had experience with ADS-B In, 85% used portable systems and 30% used installed systems.
And that's in 2019.
edit: To add and make clear, the route will be known for a training or real situation, but it will be delayed. So for training, turning off the ADS-B does not protect the route information and that is why there is no reason to fly with it off for training.
- What combat situation will require a military aircraft to be flying 30 meters from civilian jet doing routine flights?
- i don’t believe that there really is no technical solution to provide awareness to civilians of the presence and location of military aircraft without altering the pilot’s experience
- if it had told the Blackhawk crew a plane was way closer, the crew would still be alive. That’s like the whole point.
I have no expertise or n the area, but I can’t share the feeling that decision making is extremely poor, and sometimes it actually takes an outsider, who is free from groupthink and cope, to see that a decision is stupid.
Evacuating leadership during a 9/11 scenario?
> i don’t believe that there really is no technical solution to provide awareness to civilians of the presence and location of military aircraft without altering the pilot’s experience
There is. That’s ADS-B. Which broadcasts your position. So it’s turned off in military aircraft at times, for obvious reasons.
Obvious reasons to me are in active military operations against an enemy. Not flying around the airport of the nation’s busiest runway and civilian populated areas.
Surprise commandeering a civilian airfield in enemy territory.
Given that this never happened to before, requires sneaking thousands of armed men into to USA and does not achieve anything obvious besides general terrorism, why do you believe this is relevant?
And if someone did commandeer an airport, why would you evacuate the president instead of putting him in the panic room and flooding Washington with military and police?
> The entire operation lasted 53 minutes – of which the assault lasted only 30 minutes
They did not even control of the whole airport, let alone for a prolonged period of time. they got the hostages out and GTFO’d.
> Not only was the Black Hawk flying too high, but in the final seconds before the crash, its pilot failed to heed a directive from her co-pilot, an Army flight instructor, to change course.
> He told her he believed that air traffic control wanted them to turn left, toward the east river bank. Turning left would have opened up more space between the helicopter and Flight 5342, which was heading for Runway 33 at an altitude of roughly 300 feet. She did not turn left.
As much as the article tries to balance it out that the controllers should have done more it seems that ultimately the pilot flying was distracted and not following instructions from the instructor sitting next to them. It happened at least twice based on the captured recordings.
Was there something in their personal life or career to warrant that - a setback, some family situation? Otherwise they seemed qualified and flew that route a few times already.
Beyond her general lack of flight-time? Her primary role appeared to be some sort of liaison in DC, not flying Blackhawks.
That may be common for an Army pilot, but for somebody expected to fly during wartime, transport VIPs under stressful conditions, etc that's pretty goddam minimal.
From what I can tell, that's the low end of average, but that's based on 5ish mins of fact-checking.
One source among many: https://helicopterforum.verticalreference.com/topic/24169-ar...
This is one of those situations where common intuition doesn't match reality. I've similarly been wrong in the past where my intuition was off wrt/ to hours on industrial equipment compared to their expected life.
Also why is training happening in such dangerous path where even if the instructions were followed the aircrafts could get as close as 30 m apart.
I think they should prohibit such type of flights when ranks are reversed. Let's imagine he would have yanked the controls and avoided the crash. Now the Captain could have said "you're insubordinate and tanked my qualification flight, there will be a price to pay".
I am up for a good laugh, just not sure which one you meant we'd be laughing at.
> Nathan Fielder studies airliner black box transcripts in which the first officer feels too intimidated to challenge the captain, leading to fatal crashes due to pilot error. He discusses this with John Goglia, a former National Transportation Safety Board member, who had once recommended roleplay simulation to improve pilot communication.
Really good season so far!
I'd be shocked if the US military didn't provide crew resource management training for their aviators. This is exactly the kind of situation CRM is designed to prevent.
Forget training, why is this happening under any circumstances ever? If a military transport mission is ever so critical that you're willing to fly it within 30 meters of a civilian airlines it seems to me that you should just close the airspace to civil air traffic at that point.
It is far more likely to be something like cognitive overload rather than a clash or personalities - you don’t get to be in that position in the first place if you have a tendency to disregard instructors.
Yes you ease into it, the first level of training is done in a safe environment, however as the person gains competence the training moves into the domain in question, the person gains experience at doing the thing in question while being supervised. Or to put it another way.
What? You expect that their first flight through that tight corridor at night should be done alone?
In conclusion, I think it is fine in general that they were doing training on that flight path. However the fact that the both pilot and the trainer erred so badly indicates the need for better low level training and a reevaluation of the need for such a tight flight path in a civilian zone.
Update: unrelated thought, I could not decide if low or high tolerance was the term i wanted, after waffling a bit I went with high tolerance. as that is the correct engineering meaning, but really the term is ambiguous and means the different things in different domains, he has a high tolerance for alcohol means the opposite of he made a high tolerance part.
I don’t know why the instructor didn’t take a more forceful/active role leading up to the crash, but I don’t think rank was a contributing factor.
I'm not sure that's a correct understanding of how the approach path to the runway and the helicopter route are supposed to interact. So far as I understand, the intent was never that a helicopter and airplane were supposed to be able to happily barrel along their respective paths within worrying about running into each other. That kind of thing happens a lot in aviation, but the separation distance is much, much larger.
Instead, one was supposed to see the other and use their eyes to visually stay away (ideally by much more than 100 ft). That's what was supposed to happen here, and what the instructor pilot in the helicopter said they were doing. Visual separation is also used a lot in aviation, often in places where there are no narrowly defined paths at all, but it carries the risk of aircraft not seeing or misidentifying each other, which could be what happened here.
This doesn't match with how I understood the ATC's instructions. The helicopter was instructed to "pass behind" the landing airliner, not pass below. I think the controller's intention was for the helicopter to hold short of passing the runway 33 flight path, and not to enter that space until the plane had crossed the river.
I would agree in general, but in that particular environment around DC with the restricted WH fly zone, the busy airport, the river and the bridges and the ADSB switched off it can make a huge difference.
It feels like semi-autonomous ATC and flight controls were possible as of 5 years ago. Has FAA even started writing initial reports on this?
Yeah, that one has been around as long as there have been computers. It's sort of like the flying car of the ATC world - it's always 5 years away.
> temporal normal distribution to human attention spans
Tn this case we had both the ATC and the instructor tell the pilot to do something different and they didn't listen. Not sure if that's an attention span issue, it may be, but it's not clear it's definitely what it is.
Yeah, agree. There is even mention of a collision alarm at the tower going off
> Nobody gets fired for doing nothing and continuing to play whack-a-mole with human frailties.
That seems like it. It kind of feels something should have been worked out by now, but nobody wants to put a system in place, that would could due to a glitch direct a bunch of flight to crash into a mountain or into each other.
I'm a helicopter flight instructor, although I've never flown in the military. There are 5 magic words the instructor can, and I would argue is obligated to, use to fix the situation: "I have the flight controls"
Knowing they were 100 feet high and flying into the approach corridor with an aircraft on short final and not taking the controls is an enormous failure on the part of the instructor. The student was likely task-saturated and the instructor should have recognized that.
| He told her he believed that air traffic control wanted them to turn left, toward the east river bank.
Now, I'd love to _hear_ the actual comment/instruction here. He may have been hedging because he was trying to piece together the stepped on "pass behind" direction from ATC. But I also wonder if it's an inherent problem when the student outranks the instructor?
Even if they were out of the helicopter airway, based at least on radio transmissions the instructor thought they had the landing aircraft in sight and presumably thought they could stay separated from it visually. I would agree with you if staying at the exact right altitude and position was being thought of as the primary factor keeping them separated from traffic they couldn't see, but it seems different when they were operating under visual separation and thought they could see the aircraft.
That said, I fly Skyhawks not Blackhawks (or any kind of helicopter), so maybe the expectations are different in the rotary wing world. But my experience is that a 100ft altitude deviation is not an "instructors takes the controls" situation in an airplane unless you're about to run into something. Of course they were in this case, but it's not obvious the instructor knew that.
Still, very little for a fixed wing GA pilot. I know airliners use pretty low separation pretty much as a rule but they have really accurate autopilots.
Why do you focus on that and not many other possibilities for distraction - cognitive overload, lack of sleep, an injury, other distractions in the cockpit, etc.
Why shouldn't I focus on those? I guess just by asking the question you haven't quite shown why your guess are better. I guess I don't how lack of sleep is a better explainer than, I don't know, a family member dying?
I guess which one would the investigator be able to figure out? They can read the obituary of the grandmother but how would they figure she didn't sleep well the night before.
For evidence, they could ask people who know the pilot, review personal data, etc.
Well you just did above:
> and not many other possibilities for distraction - cognitive overload, lack of sleep, an injury, other distractions in the cockpit, etc.
Yeah it could be all of those and we should wait for investigation. But seems my particular guess bothered you for some reason and you suggested better guess, and I am just wondering what about my guess bothered you.
I can see if you just say "ok, let's not guess and wait for the investigation", I can agree with that.
Your attachment to reality seems a little weak: You make up a reason the helicopter pilot was (possibly) distracted, you make up my motivations. The way we intelligently distinguish fantasy from reality is evidence.
> I can see if you just say "ok, let's not guess and wait for the investigation", I can agree with that.
I thought you might have some evidence.
I simply asked you why you thought your guess were better. I was expecting, say link with statistics about "well these are the top factor contributing to the pilot error..."
> The way we intelligently distinguish fantasy from reality is evidence.
Sure, that's why my guess was something that can be validated. Your guesses are "cognitive overload" or "distractions in the cockpit". How do we prove those in this case.
> I thought you might have some evidence.
This is not a court case or scientific work, it's a discussion forum. You're fully allowed to guess, have "what if" scenarios, "wonder", complement people, talk about the weather, or the what you feel and like. That's perfectly ok. If you don't like what someone is saying or don't agree, it's best to offer an alternative, which you did but then when asked further you accused me of losing ties with reality. If you're not feeling ok, you simply don't have to reply. That's fine too.
Maybe visual flight separation is a bad idea when there are a bunch of lights from the ground and a busy airspace. A plane on a collision course with you will just look like a static light, like many many other lights in the area.
I think eventually they figured out and instructed the pilot to avoid but the pilot didn't listen. But that was the second mishap of the flight. The pilot was failing to maintain a proper altitude before that.
> Maybe visual flight separation is a bad idea when there are a bunch of lights from the ground and a busy airspace. A plane on a collision course with you will just look like a static light, like many many other lights in the area.
To me, at least in this case, it seems the pilot was not adequately prepared. They were either distracted or rusty. The instructor should have taken controls and flown back at the first sign of not being able to maintain a proper altitude. However, the pilot outranked the instructor; taking controls away and failing the qualification / training flight could have resulted in some retribution or more hassles. Also, I think they should instead let pilots do this kind of qualification in similar but more remote or less busy area, longer, until they get more hours under their belt and not allow rank reversals to train like that. They should have found someone outranking her who wouldn't have though twice about grabbing the control.
For me the most consequential factor is that the helicopter pilots (technically the instructor, but I assume both were in agreement) requested visual separation based on their obviously incorrect visual sighting of the landing aircraft, which the controller granted. While perfect adherence to the routes by both helicopter and airplane might have avoided a collision, the margin is so incredibly slim (75 ft) that it seems unlikely the intent was that it would serve as the primary way to separate traffic. Properly executed visual separation would have kept everyone safe, but it seems pretty likely that neither helicopter pilot actually has eyes on the jet, maybe at any point or maybe just prior to the crash.
I also think it's hasty to discount the controller's role. At least based on the article, it's not clear the controller provided enough information that the helicopter pilots could have determined if they had visually identified the right aircraft. Given how busy the airspace is, making sure the helicopter was tracking the right landing aircraft is pretty critical. And while it's the pilots' job, the controller can certainly give them every advantage.
I think the statement in the article about many things going wrong all at the same time is likely the right one, although of course we should wait for the final NTSB report to say for certain. I feel like people want the satisfaction of identifying one single primary cause, but most aircraft accidents don't really work like that. And we should want to understand all the factors to plug as many holes in the swiss cheese as we can going forward.
At that level a few hundred feet (since the helicopter is already supposed to be flying 200 or so feet above the ground) can make all the difference.
> I think the statement in the article about many things going wrong all at the same time is likely the right one, although of course we should wait for the final NTSB report to say for certain.

There can be contributing factors but the just because there are many factors doesn't mean they are equally weighted. At least with the pilot with have at least two indications they were confused. The instructor next to them tried to correct them a few times already.
> At least based on the article, it's not clear the controller provided enough information that the helicopter pilots could have determined if they had visually identified the right aircraft. Given how busy the airspace is, making sure the helicopter was tracking the right landing aircraft is pretty critical.
I think at least the non-flying pilot, the instructor, had understood and directed the pilot to avoid the collision, but the pilot didn't listen. The ATC in a busy airspace like don't have the time to have a long discussion with pilots ensuring they are good pilots and know what aircraft they are seeing "do you see 3 lights on it, one is red?", "how many engines do you see?". That just not very likely. They assume a helicopter pilot on that kind of an airspace configuration will know what they are doing. If they request visual separation they assume a hefty responsibility.
This is an interesting sentence. In a very generous interpretation, the pilot (if she had survived) might claim that she wasn't directed to turn, just that the instructor believed ATC wanted her to turn, and thus she still needed to evaluate the situation and decide what to do. In other words, she might claim she didn’t defy an order, because being told an instructor "believes" something is different than being directed to do it.
Trying to make sure the 'squeeze play' didn't go awry.
Being told twice the helicopter could see the CRJ and would maintain visual separation.
The built-in vertical separation rules.
A jet in landing configuration isn't in a great position to see and avoid something below it.
This is not by any means the only midair collision where a crew was avoiding a different aircraft.
