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.

Rescue crews will return to the Potomac River on Friday morning as they continue searching for victims of Wednesday night’s deadly midair collision.

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.
