The cockpit voice recorder and flight data recorder from the PSA Airlines-operated regional jet that crashed near Ronald Reagan National airport after colliding in midair with a US Army helicopter have been recovered by investigators.

A mid-air collision occurred Wednesday evening over the Potomac River involving a PSA Airlines Bombardier CRJ700 regional jet, operating as American Airlines Flight 5342, and a Sikorsky H-60 military helicopter.

An American Airlines flight crashed into a U.S. Army Black Hawk Helicopter over the Potomac River as it approached Ronald Reagan Washington National Airport.

While driving home, Ari Shulman said a "spray of sparks" in the sky caught his attention as he watched in horror the midair collision unfold.

A regional jet carrying 64 people collided with an Army Black Hawk helicopter. Reagan National Airport grounded all flights.

After an American Airlines flight and a military helicopter collided and crashed into the Potomac river Jan. 29, more than 30 bodies have been recovered, NBC Washington has confirmed.

“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.

More than 30 bodies have been recovered, two sources told NBC News, and a frantic search and rescue mission to find crash victims in the icy Potomac river remains underway.

Human-monitored Air Traffic Control, while effective in many ways, is increasingly becoming a bottleneck in ensuring safe and efficient air travel, especially in complex, high-security airspaces

This is the dramatic moment a metro train turned around when an announcement informed passengers that airport services were suspended following a crash between a helicopter and a plane. All flights were halted and search teams began scouring the Potomac River after the collision with the plane that was landing at the Reagan National Airport near Washington on Wednesday night.

None are believed to have survived the Wednesday night collision, which caused both aircraft to plunge into the frigid Potomac River.
