i think its simple, we don't have to go into all of the other evidence, but I think of it like this: we have something called radar, and when planes leave the airport, they are constantly being tracked by this. We also have something called NORAD, who's entire purpose is to stop terrorist attacks. They also are supposed to stop attacks like 9/11. But alas, even though we had all of that, no NORAD, even though those planes were off course for over 1 and 45 minutes. But other planes that have went off course and were intercepted by the military and NORAD within minutes, but not on 9/11. Why? Was radar not working that day? How about NORAD? I would love to here the excuses this time.
