Sixty-four people aboard a commercial airliner died Wednesday night after it collided with a military helicopter midair near Reagan Washington National Airport. Both the American Eagle jet and Army Black Hawk are in the Potomac River.

The Army official said that the pilots were on a routine training flight along a familiar flight path that isn't particularly complicated.

The Army Black hawk helicopter that collided with a passenger plane near Washington, D.C., was drilling mysterious 'continuity of government' plans.
