As far as I understand the News from Germany, there is no doubt at all for the German authorities and Lufthansa what happened and that the cause of this DELIBERATE crash is solely linked to the FO. The evidence so far is shocking obvious. The question is WHY and there is already one answer: we will never really know. But one could find answers to other questions, like has there been any chance for the FO to come out of his desperate state of mind? Have any warning signs been missed by others?
