Crews have begun removing wreckage from the Potomac River from the deadly midair collision last week that killed 67 people. Col. Francis B. Pera of the Army Corps of Engineers says portions of the aircraft will be loaded onto flatbed trucks and taken to a hangar for further investigation. Crews early Monday could be seen aboard a vessel with a crane. Authorities say they have recovered the remains of 55 people killed in Wednesday's collision. The crash between an airliner and an Army helicopter is the deadliest U.S. air disaster since 2001.
