All 67 people on board the plane and the helicopter were killed.
An American Airlines regional jet went down in the Potomac River near Washington, D.C.'s Ronald Reagan Washington National Airport after colliding with a U.S. Army Black Hawk helicopter on Wednesday night, with no survivors.
Sixty-four people were on board the plane, which departed from Wichita, Kansas. Three soldiers were on the helicopter.
The collision happened around 9 p.m. when the PSA Airlines Bombardier CRJ700 regional jet was on approach to the airport.
The U.S. Coast Guard shared photos of the multi-agency recovery operation in the Potomac River following Wednesday's deadly collision.
The agency said boat crews from Washington, Curtis Bay, Annapolis, Oxford, Crisfield and the Coast Guard Cutter Sailfish were responding on Thursday.
The National Transportation Safety Board said the cockpit voice recorder and flight data recorder from the American Airlines jet that collided with the Black Hawk helicopter Wednesday have been recovered from the wreckage in the Potomac River and are now at the NTSB labs for evaluation.
The runway American Airlines flight 5342 was headed towards before the deadly midair collision on Wednesday will be closed for the next week, according to a notice sent to pilots obtained by ABC News.
Runway 33 at DCA will be closed until Feb. 7, the notice said.
The flight data recorder and cockpit voice recorder -- known as black boxes -- from the American Airlines plane have been recovered and are en route to the National Transportation Safety Board lab, per a source with direct knowledge.
