His name is Andreas Lubitz, a 28-year-old German hired by the airline in September 2013. He had 630 hours of flight time under his belt.
Investigators confirm he had been medically and psychologically fit before the crash.
Reports said he took advantage of the main pilot’s exit from the cockpit. The pilot had left to ease himself only to return to find out that he had been locked out. Moments, later, the co-pilot, now on his own, put the plane in automatic descent until it crashed in the French Alps.
