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.

There were 64 passengers aboard the plane, and three Army soldiers in the helicopter, according to officials. Here's a look at what we know about the victims.
