Germanwings and parent company Lufthansa say the co-pilot had passed all medical tests and was cleared by doctors as fit to fly.
Wreckage of an Airbus A320 is seen at the crash site, near Seyne-les-Alpes, French Alps, March 26, 2015. A young German co-pilot locked himself alone in the cockpit of Germanwings flight 9525 and set it on course to crash into an Alpine mountain, killing all 150 people on board including himself, prosecutors said on Thursday. French prosecutors offered no motive for why 27-year-old Andreas Lubitz apparently took the controls of the Airbus A320, locked the captain out of the cockpit and deliberately set it veering down from cruising altitude at 3,000 feet per minute.
