A mid-air collision between an American Airlines jet and a US Army Black Hawk helicopter has killed all 67 people onboard both aircraft. Investigators are examining flight data to determine the cause, focusing on a significant altitude discrepancy between the planes. The crash occurred at dangerously low altitudes, raising concerns about air traffic management.

The American Airlines flight had 64 people onboard, and the Black Hawk had three military personnel. The black box from the commercial flight has been recovered, while the Black Hawk’s recorder was found in the Potomac River. Investigators are looking into potential air traffic control errors or communication breakdowns.

The NTSB is leading the investigation, with a focus on whether the Black Hawk was flying outside its designated altitude. Preliminary findings suggest possible issues with airspace coordination, and authorities are also examining weather and mechanical factors.

The tragedy has raised concerns about airspace safety, particularly with military and civilian aircraft operating near each other. Eyewitnesses reported seeing debris and flames after the collision, prompting emergency responses and fueling calls for stricter safety regulations.
