Hijacking is passГ©

I'm constantly aware when I'm stuck in a long security check line that I'm being delayed by a fence with more holes than swiss cheese. Any determined adversary would know that getting a job on the tarmac would allow almost unlimited access to planes and passenger luggage.

Furthermore, there will never be another successful hijacking of an American passenger airliner simply because the entire planeload will know they have nothing to lose by rushing the attackers.

And if bad guys just want to kill a few hundred Americans, there's lots of easier opportunities than hijacking a passenger plane.
