A mid-air collision between a US civilian passenger plane and a military black hawk helicopter occurred in the vicinity of Ronald Reagan National Airport.
The incident triggered a large-scale emergency response and the temporary suspension of airport operations.
As reported by the Federal Aviation Administration, Al Jazeera states that the incident took place around 9 p.m. on Wednesday.
The aircraft involved were a PSA Airlines Bombardier CRJ700, operating as an American Airlines flight, and a US Army Sikorsky UH-60 Black Hawk helicopter.
The passenger plane was carrying 60 passengers and four crew members, while the military helicopter had three personnel on board.
Al Jazeera reported an “enormous response” at the scene, including emergency vehicles and boats.
“This is the main local airport serving the Washington, DC, metropolitan area. We believe that both aircraft are in the river, which is of enormous concern.
“We were told that, at best, someone could survive about an hour and a half in this water.”
Authorities have not yet provided official information on casualties.
Video footage shared on social media appears to show the moment of impact, followed by an explosion.
Reports indicate that an air traffic controller had instructed the helicopter to pass behind the approaching aircraft moments before the collision.
Government officials, including President Donald Trump and Defence Secretary Pete Hegseth, have been briefed on the situation.
Trump stated that he had been “fully briefed” on the “terrible accident”.
Senator Ted Cruz confirmed fatalities but did not provide specific numbers.
The FAA announced that Ronald Reagan National Airport would remain closed until at least 5 a.m. on Friday.
The National Transportation Safety Board and the Department of Defence have launched an investigation into the cause of the crash.
If confirmed, this would be the first fatal incident involving a US commercial airline since 2009, when Colgan Air Flight 3407 crashed in Buffalo, New York, resulting in 49 fatalities.
