The wreckage of a military helicopter involved in a mid-air collision with a passenger jet that killed all 67 people on both aircraft was recovered Thursday from the Potomac River, federal officials said.

Crews are expected to remove the cockpit from the American Airlines jet from the Potomac River as they continue recovery efforts from last week's fatal mid-air collision that killed 67 people.

Crews spent the weekend positioning cranes and other key equipment following last week's deadly plane crash near Washington, D.C.
