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.

Video recorded by bystanders shows the harrowing moment when the 2 aircraft crashed into one another, causing an explosion over the nation's capital.
