The cockpit doors are locked now and the lack of those locks is what allowed the 9/11 hijackers to gain control of the planes and the crashes to happen. Also, two people are required in the cockpit at all times. These TSA idiots seem to be able to find and confiscate nail clippers and corkscrews but can't seem to find bombs and guns. Does anyone seriously believe that after 9/11, passengers would sit idly by while a couple of maniacs with scissors, nail clippers, screwdrivers, or corkscrews take over the passenger cabin? A poster at another forum told a story about the time he had a 6-way screw driver in his computer bag. The TSA took it away, of course. But then he heard someone run up behind him yelling 'Sir! Sir! Look... If you break down your screw driver into the basic parts then none of them are more than 4" long. As long as you leave it in parts you can take it on with your carry-on.' I mean SERIOUSLY?
What they need to focus on is finding bombs and firearms and screw everything else, but evidently even that's too hard for them.
