El Al has sturdy doors. As far as a self destruct program goes. what makes the difference if the pilot blows it up or the terrorist does it? Also, if they say they will blow it up, what would be gained by opening the door?

Sealing the flight crew (no 'bloody' doors at all) will not prevent self destruction (bombs) as I said in my first post on the subject, but it would have and will prevent passengers with basic weapons from making threats, from controlling the aircraft and where the bomb explodes.

What are the good and pressing reasons for not taking this action, in addition to the other increased sucurity measures?
