I saw a video of an abc world news tonight where they reported on NORAD doing simulations of terrorist attacks with airplanes on the day of 911. Peter Jennings reported it, and possibly had a liberal spin or something intended. But whether it was done on exactly 911 or any time before, it still shows that an attack like this was at least considered possible. Whats hard to believe about terrorists wanting to crash planes into the two most arguably recognizable buildings? That seems elementary to me. They tried to blow it up once before for crying out loud. NORAD is to defend US ( North American)airspace, not whats going on "over there-off us soil." All of the planes did'nt strike their targets simultaneously. There was something like 20 minutes from the first jet hitting, the second jet, and some time later the pentagon was hit. Why Pres. Bush sat in that stupid classroom for 15 minutes after being informed of the attack is beyond my understanding.
