I don't doubt this was a FF, and I do agree that there's more going on here than we've been told. What I wonder, and the thing I've never seen addressed, is how they had all the people set up to do the phone calls, as with the guy on flight 93 (the one in Pennsylvania) talking to his wife and all the calls to 911. That's an awful lot of people to have playing a part in the FF. I don't doubt it's possible to do this; I just wonder how it was done.
