I believe the German pilot would not have carried out his murderous intentions if a FA had been on that flight deck with him.
I agree, I think he would have done it at 200ft with the Captain sitting helplessly beside him.
What is different about their entry into the flight deck when a pilot needs a wee, to their entry when a pilot receives their lunch?
One situation is 2v 1, the other situation is 1v 1.
In the 2v1 neither of the 2 have shoulder harnesses on.
In the 1v1 one is in a five point harness and can't see the other directly behind them and is also required to be looking forward for most of the time.
You say " the German wouldn't have done it if a F/A was there. " In a few years time will you or someone else be saying " the F/A wouldn't have done it if the other pilot was there" .?
It works both ways, it's just that we are exposed to much lower numbers if it's just pilots. A lot fewer brains have to be 'healthy' if we are just trusting the pilots .
