Officials have recovered and identified 55 victims as third Black Hawk pilot identified - None of the 67 passengers and crew are believed to have survived

Preliminary data from the Washington DC air collision that killed 67 people gives conflicting information about the altitudes of the plane and military helicopter at the time of the crash.

An American Airlines regional jet went down in the Potomac River near Ronald Reagan Washington National Airport after colliding with a U.S. Army Black Hawk helicopter, Wednesday night, prompting a multi-agency search-and-rescue operation, according to officials.
