Doors can be opened before a crash. The reason security doors are not on us airlines is a business decision. It was pointed out on another thread that secure doors may already be an option that the Boeing company offers on its products. >>Air Traffic Control; is it true that, when a transponder is turned off(and btw, why is it that a transponder CAN be turned off, anyway) the ATC argues that it is too difficult for them to track aircraft with other instrumentation. Does this mean that if a switch is simply turned off in the cockpit, ATC has "lost" the aircraft. It appears from the time lag btw the World Trade Center attacks and the Pentagon/Pittsburg crashes, ATC was clueless for about ONE HOUR. No military jets were scrambled to protect our seat of power in Washington for ONE HOUR after the first WTC attack(8:45am WTC #1 to 9:45am Pentagon). Transponders on airliners could be automated to be on all the time. They could install two more transponders as backups. ATC Radar still tracked those planes after the transponders were shut off. That's what radar is for. Fighter jets were scrambled but too late, and I believe they flew from Massachusetts. Since the attack, fighter jets are in the air patrolling the skies over the major cities. Intercept times should be minutes. I think ATC and Air Defense are going to be a little more integrated in the future -- this might be as simple as having the Air Defense phone number on speed dial in the ATC towers and regional centers. BTW all flight schools are effectively closed now for basic in flight instruction. Lots of flight instructors out of work.
