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.

As per the latest press conference from the Washington DC Fire Chief, all 64 passengers on the American Airlines plane are feared dead. Rescue operations remain ongoing as 27 bodies have been recovered from the river.

This afternoon the NTSB held its first briefing on the crash saying this was a very quick and rapid impact. Since Wednesday night they have been dealing with difficult conditions. Despite that, the DC fire chief says he is confident the remains of everyone involved will be found.
