Not sure if it's a translation issue but this jumped out on the GW own press release:
26.03. 07.30 p.m.: Daily summary, 26 March 2015A few hours ago we thought last Tuesday was the darkest day in the history of our company. But today, Thursday, has been no less devastating.
We were stunned to learn today that the airplane we lost in southern France was to all appearances made to crash by deliberate act—presumably by the co-pilot. This is evidently the conclusion of the French investigative authorities who have studied the voice recorder that was recovered from the ill-fated Airbus A320. It appears that, once the plane had reached cruising altitude, the captain stepped out of the cockpit but was unable to re-enter it a short while later, as the co-pilot had bolted the cockpit door.
(Bolding mine)
Is this just a reslt of translation from German to English, or actually what they mean? because if so that is very different to denying entry via the normal method....
