An American Airlines jet and an Army helicopter collided over Washington, D.C., Wednesday night. All 67 people aboard the aircraft are presumed dead.

Victims' families gathered near the site where a plane and copter collided and fell into the Potomac River. 'They are all hurt,' an official said.

The U.S. Army has named the third service member who died in the collision between a Black Hawk helicopter and a commercial plane.
