On Tuesday March 24, a plane crashed in the French Alps traveling from Barcelona, Spain. All 150 people who were on the plane died in the crash, including six crew members and sixteen school children. Four Americans were also on board the crash when it happened.  New revelations reveal that the copilot intentionally crashed the plane.

The black box containing recordings of conversations within the cockpit was recovered recently revealing disturbing information about the crash. According to Lufthansa Airlines, it appears that the co-pilot, Andreas Lubitz, was suffering from Depression and Burnout in 2009. He then apparently took a break from his training as a result of his burnout and overwhelming workload. Lubitz had 630 hours of in-flight hours at the time of the crash, while the main pilot, Patrick Sondenheimer, had over 6000 hours of training and total in-flight hours over the course of ten years.

The black box also revealed that Lubitz had locked the door to the cockpit and did not allow Sondenheimer back into the cockpit, despite Sondenheimer’s repeated efforts to break the door down. There was no noticeable noise coming from Libitz in the recording, but there was a considerable amount of noise from the panic of passengers and the crew locked outside the door.

Other evidence includes air traffic reports, which state that Lubitz did not respond to any report requests and had set the autopilot setting for the plane to go 100 feet above ground before the crash. This was the lowest setting that could be possible for the autopilot system of the aircraft.

The city of Haltern am See, North Rhine-Westphalia was said to have lost sixteen schoolchildren and two teachers. Mayor Bodo Klimpel stated that this was “the darkest day in the history of our city.”

Current investigations have begun on the house of Lubitz. President Barack Obama was said to have offered U.S. assistance for investigations, which has not seen response so far.
