Something seriously fails to add up with this story.
He may have had the Means to crash the Plane (He was a Pilot), he may have had the opportunity (he was alone in the Cockpit) by nothing remotely credible as a motive has yet to be presented.
Most damning of all was the French Prosecutors description of the Co-Pilots based on the Cockpit recordings; he made no noise and was BREATHING NORMALLY ............ WHAT!!!!!!!
So are we really being asked to believe that somebody was so depressed that they decided to end it all and take everybody else with them and that nobody; in an industry extremely sensitive to such conditions among Air Crew, actually noticed!!!??
Impossible. Sorry utterly impossible. I have had experience of seriously depressed and suicidal people and it does not reach crisis overnight and it very soon becomes crystal clear that something is seriously wrong, even to ordinary people who are neither trained to recognise the symptoms, nor actively looking for them.
Then what a sudden rage? A "I'm as mad hell and I'm not gonna take it any more" moment?
Clue is in the Mad as Hell part. No way would somebody in that mind frame sit quiet for 10 minuets, especially with others shouting and banging at them from outside. If your that pissed at something, I think you would be using every moment of those last minutes to let everyone and anyone know what you thought about things and why.
Finally, "Breathing Normally"!!! No Way, Happy, Angry, Sad, Mad, Bad or simply Dangerous to Know, but not even James Bond could deliberately fly a Jumbo into the ground and breath normally. Its not possible .... period.
Plus it is of course, another unconvincing Air mystery.
So here is an idea. There is is a serious security/safety vulnerability in Commercial Aircraft and nobody in authority is prepared to admit it.
