Families and friends of those who lost loved ones in the deadly American Airlines and Army helicopter collision are sharing tributes online in memory of the crash victims.

Two days after an American Airlines flight crashed in Washington, D.C., an air ambulance carrying six passengers—including a pediatric patient—crashed down in Northeast Philadelphia.

An Army Black Hawk helicopter collided with a regional jet near Ronald Reagan Washington National Airport on Wednesday evening, U.S. officials confirmed to ABC News.

Grainy video footage taken in the dark of night, seemingly by an airport CCTV camera, appears to capture the moment American Airlines Flight 5342 was in collision with a U.S.

The search and rescue mission was transitioning to a recovery mission, and no survivors were expected, DC Fire and EMS Chief John Donnelly said.

The Black Hawk helicopter that crashed into an American Airlines flight was alerted to the plane’s presence by air control twice, according to the reports.

Investigators found the recording devices, or black boxes, from the American Airlines plane that collided with a helicopter Wednesday near Washington.

The FAA and NTSB have launched an investigation into how an American Airlines flight collided with a military helicopter over the Potomac River.

Business Insider reviewed official briefings, flight data, and air traffic control audio tapes to piece together what happened before tragedy struck.
