Settle down guys. Every field of endeavour has its idiots and aviation is just another. I'm not condoning what happened or glossing over the tragedy that has befallen the families of the murderer and his victims and the victims themselves. What I am saying is that if anyone wants to bring down an aircraft enough, they will. Having a young stewardess 'baby sitting' a body builder of a pilot with suicidal tendencies is unlikely to prevent another tragedy. There is no silver bullet to solving this problem, which isn't a particularly common one, because if you prevent the door being locked from the inside, you make it easier for terrorists to force access. Sky marshals with guns? Great idea. However, what happens if the marshal is a Muslim, (applicants cannot be rejected on religious grounds) who later becomes radicalised? Far fetched? probably. Possible? Yes. Speaking from experience, if I am faced with an emergency in the aircraft or sim, my personal motto is 'be there and cope'. That's all we can do because every situation is dynamic and different and we have to flexible to deal with whatever is thrown at us, to bring about a successful conclusion in any way we can. The situation for pilots, cabin crew and the airlines is exactly the same, whatever happens, 'be there and cope' and sort the situation out. I for one don't want to die in an aircraft crash and every pilot I know has the same attitude and we will do whatever we can to prevent it happening and the chances are, if we survive then our passengers will too. There is an inherent risk in flying and there always will be.
