Plane and helicopter wreckage being recovered in Washington

Search teams on the Potomac River in Washington are working to recover the wreckage of a plane and helicopter that collided in mid-air last week.

Fifty-five of the 55 victims of the accident have been identified, and the Washington Fire Department said "the bodies of all victims will be recovered."

More than 300 people are participating in this campaign, officials said.

The accident occurred when the plane collided with a military helicopter at low altitude before landing. There were no survivors.

Among the passengers on the plane were figure skaters returning from the U.S. Figure Skating Championships and a group of hunters.
