The incident was the deadliest aviation crash in the U.S. in more than two decades. There were no survivors. The remains of all 67 victims in the Washington, D.C., plane crash have been recovered as of Tuesday, nearly a week after an American Eagle flight out of Wichita, Kansas, collided with a Black Hawk helicopter midair.

The aircraft was on a mission, providing intelligence, surveillance and reconnaissance at the request of US Philippine allies.
