There is also another element to this: the passengers. I don't want to sound crasse, but the people on Flight 93 are TRUE American heros precisely because they stood up to their hijackers. I get misty just thinking of the b*lls that a regular guy like Todd Beamer had. His "Let's Roll" comment is really the battle cry of every passenger that travels on the airlines.
Fact: The passengers will no longer be passive. Now that they understand that they are dead no matter. They now realize that these Muslim fanatics will kill them, their children, whoever --that is what Muslim fanatics do (they are cowards).
There was a story where a pilot (airline?) instructed the passengers on PRECISELY what to do if a hijacker were to attempt a takeover...I can't find the link. Basically, it was bum rush him and beat the crap of him. Every pilot should be required to read that, instead of the stupid "Here's the exit" speech.
The next attack will not be with a commercial airplane. The next attack will be devastating, there will be lots of people dead (primarily because of the demoNUGGETs emasculation of the intelligence services), but it won't be done with a commercial airliner.
I hope there isn't another attack, but with a$$holes like Osama, Yasser, and SoDamn Insane running around the world, we are looking at that proposition.
Sounds like some good, old-fashioned "wet ops" are in order!
