The NTSB and FAA are briefing members of the Senate Commerce Committee on Thursday on the ongoing crash investigation.

The Black Hawk helicopter that collided with a passenger jet in Washington on Wednesday was on a training flight along a route core to a seldom-discussed military mission to evacuate senior officials to safety in the event of an attack on the U.S., officials say.

More than a week after the deadly collision of a passenger jet and a helicopter, crews forged ahead with salvage efforts in the Potomac River.

Divers and salvage crews have recovered the remains of all 67 victims of last week’s midair collision near Reagan National Airport, officials said Tuesday.

Every victim involved in the American Airlines commercial plane collision with a military helicopter last week has been recovered. Officials announced Tuesday that the remains of 67 people — 64 from the plane and three from the helicopter — have been recovered.
