Straight answer--I'm just an ordinary citizen near retirement who did ROTC and the Vietnam thing in a Helicopter Ambulance unit.
There seems to be a fairly strong case that AQ and the US were somehow partners in getting the Russians out of Afghanistan. Discovering as a young 2Lt how the CIA really worked, I can imagine how deep and how long our ties to AQ really are.
There are so many factual problems with the official story regarding the events of the day at WTC and elsewhere that it simply cannot be true. Not trying to hijack or derail the thread. It's just a straight answer.
So if the story cannot be true, it is not true. It cannot be proved that any aircraft were hijacked that day, and 2 of the 4 were not even where they were supposed to be.
No sir, AQ was not "behind" the attacks, though it is certainly possible that they played along with their previous handlers. I don't know the details because I wasn't in on it.
