The National Transportation Safety Board says it has recovered a cockpit voice recorder and flight data recorder from the American Airlines plane that collided with an Army Black Hawk helicopter near Reagan National Airport late Wednesday.

There are confirmed fatalities from the collision of American Airlines Flight 5342 and the U.S. Army Black Hawk helicopter over the Potomac River. Several bodies have been pulled from the Potomac River crash site, according to two law enforcement sources familiar with the ongoing operation.

“A PSA Airlines Bombardier CRJ700 regional jet collided in midair with a Sikorsky H-60 helicopter while on approach to Runway 33 at Reagan Washington National Airport around 9 p.m. local time,” the Federal Aviation Administration (FAA) said in a statement.
