WASHINGTON ā A series of grave miscommunications in one of the most crowded and complex patches of sky in the US likely causedĀ Wednesday nightās deadly midair crashĀ between an American Airlines passenger plane and a US Army Black Hawk helicopter near Ronald Reagan National Airport, The Post can reveal.
The crash, which killed all 64 people aboard the packedĀ Flight 5342 from Wichita, Kansas ā plus three people on the chopper ā is the deadliest US air disaster since 2001.
Less than 20 seconds before the collision, an air traffic controller warned the chopper that it was getting too close to the CRJ-700 passenger jet, and the experienced helicopter pilot acknowledged.
However, experts believe the helicopter pilot may have maneuvered to avoid the wrong plane ā a jet of the same model that was taking off farther away ā and never saw the American Airlines flight until it was too late.Ā
The Black Hawk helicopter was apparently flying too high ā at about 400 feet ā when it collided with the American Airlines jet, which was rapidly descending after it was cleared for landing, experts said.Ā
However, because of the close quarters around Reagan National ā there is just 50 feet separating the maximum allowable altitude for helicopters and the minimum altitude for planes that are landing in the spot ā leaving almost no room for error.Ā
Officials have not yet offered a possible cause for the crash, however, Transportation Secretary Sean Duffy said Thursday that the tragedy was āabsolutelyā preventable.
The Post spoke to several aviation experts about a number of factors that may have contributed to the fatal collision.
Originally built to shuffle VIPs into the nationās capital on private or government jets, Reagan is a smaller airport than Dulles or Baltimore/Washington International ā the other two airports in the region.
With a runway nearly half as long as the standard 13,000-foot runways of other airports built to accommodate large commercial jets, landing is tricky for incoming planes,Ā former DC-based American Airlines pilot John WrightĀ said.
āWhen it was originally built [in 1941,] there werenāt jet airplanes, which need to take a lot more space than propeller-driven airplanes,ā he said.
The shorter runway makes the descent difficult, creating the need for pilots to be intensely focused, Wright said.
āThe first few times you fly there, you usually are with [a fellow pilot] whoās really experienced. Heās kind of talking through it, too,ā he told The Post.

āWhere you land on [runways] that are 13,000 feet long, youāve got plenty of room to play with. But at [Reagan] itās only 7,000 feet.ā
There are two flight paths in the area ā one for helicopters and another for airplanes ā that converge near the Reagan airport, according to an official flight map.
Air traffic controller audioĀ captured operators warning the military helicopterĀ that it was getting close to American Airlines Flight 5342 and directing it to pass behind the passenger plane, which would have had the right of way for the trickier landing.
āItās such a challenging airport to land a jet airplane,Ā asĀ your focus is really on your airspeed, your altitude, your rate of descent,ā he said, adding that āthe last thing youāre looking for is to see if somebodyās crossing in your path.ā
Still, he insisted, āitās totally possible to operate safely at Reagan International ā I did it for 50 years, of course.ā
Another complicating factor could be the too-general nature of the air traffic controllerās language to the Black Hawk. In video of the collision taken from the Kennedy Center, a second jet is seen in the sky taking off at the same time as the DC-bound flight was attempting to land.
Instead of providing specific information of where the Wichita airplane was, the controller only asked the military pilot if he saw the āCRJā ā the type of airplane ā in the sky, without indicating where it was.
āThe language is usually more along the lines of ⦠āBlack Hawk, hey, do you see the aircraft at your 11 oāclock, five miles out, moving north?ā or something along those lines,āĀ Ā retired Blackhawk pilotĀ Lt. Col. Darin Gaub told The Post.Ā
He added: āThat may be something thatās going to have to get looked at, because in my experience, those kinds of calls and warnings are made very specifically to clock direction, distance and altitudes and in route of travel.ā
But former Air Force pilot and Rep. Adam Kinzinger (R-Calif.) claimedĀ in a video posted to X on Thursday that āair traffic control did its jobā by merely alerting the helicopter of the CRJās approach.
āIf you listen to the audio, the [commercial jet] was coming in on approach [when air traffic control] called out to [the army helicopter, ālook for the [jet] on approach ā thatās air traffic controlās job,ā Kinzinger explained. ā[The helicopter] evidently saw the wrong target ā this is the theory ā and said, āI see the [airplane.]āā
Visibility was likely also a factor, though it was a clear night at the time of the crash.Ā Gaub said there are typically two soldiers on board a Black Hawk who help spot area aircraft for helicopter pilots ā but Thursdayās flight had just one.
āThere are normally two crew chiefs in back, both looking sideways 90 degrees off from the front two pilots, and each one of them is a set of eyes that can see a whole lot more, in some cases, than the pilots can,ā he told Fox News on Thursday.
āIf youāre down to [crew members] ā which is normal, by the way, for a training mission ā that one side has less eyes looking out and looking for other aircraft or obstacles than you would have with four.āĀ
Another issue that may have been a factor in the helicopter crewās visibility was their possible use of night-vision goggles, Gaub said.
ā[Night vision] takes your normal field of vision from what you see normally to down to about a 40-degree [angle,] and that affects each pilot in the front.
He notedĀ thatĀ commercial aircraftās lights may have āblended into the lights of the city, and it can make an aircraft difficult to pick out.Ā
āIāve had it happen to me before,ā he told The Post. āI know exactly how it looks, and you can lose an entire 747 in the lights of a big city.ā
The helicopterās altitude may also have played a role in the collision, as helicopters are directed to fly no higher than 200 feet in their path ā and the collision happened at roughly 300 feet.
āIf the helicopter was flying at an altitude that was higher than what is prescribed and dictated by procedure through that airspace corridor ⦠they could have been looking at an aircraft that was ⦠potentially even below their own altitude,ā Gaub told The Post.Ā
Even if the helicopter had been at its 200-foot maximum altitude,Ā aircraft aviation attorney and former pilot Jim Brauchle explained thatĀ there still would not have been much space between it and the commercial jet descending from its 500-foot ceiling.
āYouāve got intersecting routes that are apparently de-conflicted by, you know, only several hundred feet ā which is not a lot of room for a margin of error.ā
Whatās more, Federal Aviation Administration rules allow pilots a standard 75-foot deviation from the prescribed altitudes, which could potentially drop that margin even lower, Brauchle said.
Regardless, WrightĀ said the helicopter āshould not have been crossing the flight path at any altitude at that time.ā
āSomehow something broke down between the helicopterās clearance to be there and the air traffic control tower,ā the former pilot surmised.
āIt kind of seems like a very preventable accident that shouldnāt have happened if normal procedures were followed.ā
