More of the wreckage of an American Airlines regional plane was recovered Tuesday from last week's deadly midair collision over Washington, D.C., that sent the airliner and an Army Black Hawk helicopter crashing into the Potomac River.

Even as crews continued to comb the Potomac River for victims' remains, the Army Corp of Engineers began recovering the wreckage of the midair crash.

Crews have removed the first pieces of wreckage from the American Airlines plane that collided midair with a U.S. Army Black Hawk helicopter near Washington, D.C., last week. CBS News senior transportation correspondent Kris Van Cleave has the details.
