Data from a cockpit voice recorder of the Black Hawk helicopter that collided with an airliner near Washington, D.C, last week suggests the crew was wearing night-vision goggles.

In images shared by the NTSB, the crumpled metal that was once a working military helicopter can be seen being lifted from the water by a crane floating atop a barge in the Potomac River.

Sixty-four people aboard a commercial airliner died Wednesday 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.
