An American Airlines regional jet went down in the Potomac River near Ronald Reagan Washington National Airport after colliding with a U.S. Army Black Hawk helicopter, Wednesday evening, prompting a multi-agency search-and-rescue operation, according to officials.
The airport will be closed until at least Friday at 5 a.m., according to the FAA.
The Federal Aviation Administration reported that preliminary information suggests a PSA Airlines Bombardier CRJ700 regional jet was involved in a midair collision with a helicopter while approaching the airport at approximately 9 p.m. local time.
The military chopper had three soldiers on board and was not carrying any VIPs, a defense official told CNN. The Black Hawk can carry 15 people, according to Fox News.
The airline confirmed that 60 passengers and four crew members were on board.
The U.S. Army Black Hawk helicopter that collided with American Airlines Flight 5342 over the Potomac River was on a training flight at the time, according to Heather Chairez, spokesperson for Joint Task Force-National Capital Region.
American Eagle Flight 5342, operated by PSA Airlines, was traveling from Wichita, Kansas., to Washington when it collided with an Army Black Hawk helicopter on approach, according to the New York Post.
"We can confirm that the aircraft involved in tonight’s incident was an Army UH-60 helicopter from Bravo Company, 12th Aviation Battalion, out of Davison Army Airfield, Fort Belvoir during a training flight. We are working with local officials and will provide additional information once it becomes available."
First responders have pulled 18 bodies from the Potomac River following the crash.
The devastating toll was as of 11:30 p.m., CBS News reported, citing an official.
No survivors have been found yet, the outlet reported.
