An American Airlines regional jet went down in the Potomac River near Ronald Reagan Washington National Airport.

Officials say the conditions of the Potomac River are complicating recovery efforts of the bodies of the 67 presumed dead in a mid-air collision between American Airlines flight 5342 from Wichita and a military Black Hawk helicopter.

On Saturday, officials are bringing salvage equipment to help remove the passenger plane and helicopter and retrieve the rest of the bodies.
