Sixty passengers and four crew from the plane are presumed dead from the crash, which also killed the three military members in the helicopter.

An American Airlines plane and a U.S. Army helicopter collided near Reagan National Airport and crashed into the Potomac River, according to officials.

A US Army official said the helicopter involved was a Black Hawk model carrying three soldiers. They had been on a "training flight," a separate military spokesperson said in a statement.
