Let's see, four knife wielding hijackers on the flight. Captains says "everybody remain in their seat and the seat beat sign will remain on". Hijackers think "Gee, we better seat here and not move or we will get in alot of trouble."
That has to be the silliest thing I have ever heard. If you are willing to kill yourself by crashing a plane into a building you are not going to sit there and follow the captains orders. These announcements only serve to distress passengers and possibly make them more uncomfortable. They certainly are not going to prevent a hijacking.
I think that Captain and crew should be as nice a possible to all passengers as they are the ones who can make a difference if a hijacking attempt is made.
