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. Army helicopter

A midair collision between an Army helicopter and an American Airlines flight killed all 67 people aboard the two aircraft, officials said Thursday, as they scrutinized the actions of the military pilot and reported that control tower staffing was “not normal” at the time of the country's worst aviation disaster in a generation.
