The staffing at the air control tower at Ronald Reagan Washington National Airport was "not normal" when an American Airlines plane and an Army helicopter collided on Wednesday night, a report shows.

Officials say there are no survivors among the 67 passengers on the aircrafts that collided above Washington, D.C.

Ari Schulman told NBC Washington that he saw the plane crash while driving on the George Washington Parkway, which runs along the airport. He said the plane's approach looked normal, until he saw the aircraft bank hard to the right, with "streams of sparks" running underneath, illuminating its belly.
