It appears as though from these posts that there really are some precious and fragile ego's on the flight deck...and for a group of people who are supposed to be able to look outside the square that would not be the case with several people posting here...
fmcinop....You and some others are making several assumptions which is not always a good idea with flying or aviation in general.
Who is to say that a pilot is thinking and acting rationally?
Who is to say that it is not their aircraft but another aircraft that they intend to put in harms way by using an explosive device?
Who is to say that they don't want to take the risk that the other pilot might be able to stop them if it is their aircraft?
I agree that all people who have access to aircraft be subjected to security but there is no reason to prevent pilots from that same scrutiny....
