All the major pieces of the wreckage of American Airlines Flight 5342 and the Black Hawk army helicopter that crashed over the Potomac River last week have been removed as of Thursday, according to military officials.

Salvage crews have recovered the last large pieces of aircraft wreckage from the Potomac River on Thursday and are focusing on collecting small pieces from the crash site where 67 died.

Search teams scoured the Black Hawk helicopter wreckage after the Potomac River mid-air collision with a plane. A group of investigators conducted an inspection in the frigid waters where the military chopper crashed into a plane before plunging into the Potomac River.
