There are aguments for and against the case against Capt Mason, personally I think that he did the wrong thing but with the best of intentions! I say this because no matter what the situation, the only people that really need to be in a flight deck are the crew. It may seem that this is a harsh view point, but who knows who you are on-board with nowadays!!!! Even Mr.Savage may be a threat to security- as mere citizens, who are we to know.
But then when looking back, having been lucky enough in the past to sit up front for many flights, it is dissapointing that this is not possible anymore, but then as a passenger, i think i feel safer knowing that the door is locked and only the pilots have access o the controls.
From a passenger point of view it is very disconcerting to see an "alien" entering the flight deck after 9/11, as you are unsure of who they are!
