Pieces of wreckage from the American Airlines flight that crashed into a helicopter above the Potomac River have been removed from the water. On Monday, crews from the U.S. Army Corps of Engineers used large cranes to remove the wreckage of the jet that was part of the deadliest U.

The Army Corps said it is first salvaging the jet — which still is believed to have bodies in it — and afterward, it will recover the fallen Black Hawk.
