Sixty-seven people died in a collision between a Bombardier CRJ700 regional jet operated by PSA Airlines and a military Black Hawk helicopter.

NTSB officials say recorders from both aircraft have been recovered in good condition as the investigation into the crash continues.

Some have suggested that it stems from Hussenot's device because it used film and "ran continuously in a light-tight box, hence the name 'black box,'" according to Airbus, which noted that orange was the box's chosen color from the beginning to make it easy to find.

The U.S. Army helicopter that collided with an passenger jet near Washington, D.C., had an advanced surveillance system turned off.
