Investigators are still trying to determine the cause of the Germanwings crash the morning of Tuesday, March 24, that resulted in the loss of 150 people — 6 crew members and 144 passengers — who were traveling from Barcelona in Spain to Düsseldorf in Germany.
Theories about the reason for the crash include the possibility that the plane suddenly lost altitude, perhaps because of a technical issue, fire or explosion, and the pilot could not unlock the door because he was attempting to prevent the crash. The pilot might also have been unconscious because of a sudden drop in cabin pressure.
Terrorist action has not been ruled out. The gradual descent seems to indicate human intervention even as French Interior Minister Bernard Cazeneuve reassured the public that terrorism wasn’t a “likely hypothesis” at that point in the investigation.
