I find it fascinating that so many people seem to think that it would be so simple - almost automatic - to scramble armed fighters to shoot down American civilian airliners, full of civilians and possibly (to the knowledge of the AF/ANG) hijackers, on a chaotic day, when an hour before the threat level was not elevated. They seem to equate them with Bears inbound over the pole or something.
Fortunately such people aren't generally in charge of making life-and-death decisions - usually something more like what toppings to ask Mom to get on the pizza.
Yeah, I'm sure it's real complicated stuff. I'm sure military brass never imagined, planned, or drilled for such a scenario prior to September 11, 2001...
Ha, ha, ha... you government truthers will conjure up just about any excuse you can think of to deflect blame away from your beloved criminal government.
