Investigators have already recovered the cockpit voice recorder and flight data recorder of the American Airlines plane that collided with an Army helicopter near Ronald Reagan 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.

WASHINGTON — More than a dozen bodies have been pulled from the Potomac River after a plane collided with a military helicopter in midair and crashed into the Potomac River near Ronald Reagan Washington National Airport (DCA) on Wednesday night.
