The Army Black Hawk helicopter that collided with an American Airlines commuter plane near Reagan Washington National Airport in Virginia Wednesday was on a “training flight” when it crashed into the Potomac River, according to the military service branch.

A few minutes before the jet was to land, air traffic controllers asked American Airlines Flight 5342 if it could do so on a shorter runway, and the pilots agreed. Controllers cleared the jet to land, and flight tracking sites showed the plane adjust its approach to the new runway.

According to the FAA, an Army Black Hawk helicopter collided into a 60-passenger flight landing at DCA midair.
