Please. Don't become a Raimondoite. You will marginalize yourself right off this forum.
Wait a second. Isn't our national defense system supposed to be able to scramble a plane within 5 - 10 minutes anytime a plane is hijacked for any reason? Shouldn't all 4 of those planes have had fighter escorts long before they reached their targets? We didn't need to know that it was Islamic fanatics on board. (But in fact we did. The airlines had the names available before they hit the WTC.) Just the fact that the planes were hijacked should have sent the system into action immediately. Where was our defense when we were actually under attack?
