SEYNE-LES-ALPES, France — Two Americans were believed to be on board the Germanwings plane that slammed into a remote Alpine mountainside, the airline said Wednesday, as investigators continued searching for clues on what caused the crash.
French officials said a black box recovered from the ill-fated plane — Flight 4U9525's cockpit voice recorder — was damaged but could still shed light on what prompted the Airbus A320 to descend rapidly and crashing into the Alps, killing all 150 people aboard. Some Germanwings crew members have refused to fly following the unexplained accident.
French Interior Minister Bernard Cazeneuve acknowledged that all possible explanations for the crash are being considered, but told RTL radio that terrorist action is not the most likely theory.
