It was reported by MSNBC that a friend of Lubitz’s said he had taken a 6 mos leave of absence from Lufthansa recently because of “burn out” (even though he had only 600+ hours of flying at the time of the crash). It could be that if it was a deliberate act that he may have suffered some kind of psychotic episode, a breakdown. He had returned to work passing a physical, flying test, etc. but had not undergone psychological testing which they said was a requirement for being first hired, but not done after.
