French rescue crews have located the downed Germanwings A320’s black box recorder, a critical piece of equipment that could shed light on what led to the plane crashing Tuesday in southern France with 150 people aboard. The airliner, whose debris was discovered in a remote, snowy region of the French Alps, crashed Tuesday shortly after takeoff in route from Barcelona to Düsseldorf.

"A black box that we found a few hours after the crash will immediately be examined to help the investigation move forward quickly," French Interior Minister Bernard Cazeneuve told reporters Tuesday.
