The copilot who crashed Germanwings Flight 9525 reportedly hid a health condition from his employers that would have deemed him unfit to fly.
According to Reuters, investigators found numerous doctors' notes in Andreas Lubitz's home stating that the 27-year-old shouldn't have been at work the day he flew a plane into the French Alps and killed 150 people.
German prosecutors said,
Lubitz is said to have entered a depressive state six years ago when he postponed his training to become a pilot.
He allegedly took six months off in 2009, and Reuters reports he might have received psychiatric treatment for depression and anxiety for over a year.
Mental health problems didn't seem to be an issue when Lubitz went back to training, however, said the CEO of Lufthansa, which is the airline that owns Germanwings.
Lufthansa CEO Carsten Spohr said on Thursday,
The Metro reports this depressive episode could have been triggered by a breakup with a girlfriend, but many acquaintances of Lubitz had only good things to say about him.
Klaus Radke, who runs the flight club in Germany,
A friend told Reuters, however, Lubitz became increasingly silent and began talking less and less.
The friend said,
Lubitz is believed to have committed the mass murder after locking the captain of the Germanwings flight out of the cockpit when he had exited, most likely to use the bathroom.
Numerous airlines such as Norwegian Air, Britain's easyJet, and Air Canada now require two crew members to be in the cockpit at all times, protocol most US airlines already follow.
If a pilot needs to exit, Mashable reports, a flight attendant must be present in the cockpit until he or she returns.
Lufthansa has not declared whether it will implement this rule.
