It seems incredible that a pilot of a passenger airline could be locked out of the cockpit. But analysis from the cockpit voice recorder recovered from Germanwings flight 4U9525 after it ploughed into the Southern Alps in France has revealed that this is what happened and that one of the two pilots had been trying to get into the cockpit before the crash.
An initial explanation that the pilot at the controls was incapacitated, perhaps from a heart attack, has since given way to an alternative given by French investigators: that the co-pilot in the cockpit – named in reports as Andreas Lubitz – deliberately prevented the captain from entering in order to destroy the aircraft.
