> I think what's really preventing future 9/11 attacks is the attitude of the passengers. I'm certain of this. The scheme used on 9/11 was a one-and-done affair. It cannot be repeated. We know this because only one hour after the first plane hit the north tower of WTC, that infamous "let's roll" line was overheard on a phone call from Flight 93. Not only are future attempts at this unworkable, not even the 4th attempt of that day was viable! Airport screening should be for bombs or other materials that cannot be countered by passenger resistance. Drugs, pocket knives, darts, etc. should be passed through without comment. This would also improve the effectiveness of the screening! With fewer items to be on the lookout for, the screening can be more effective.
