Funny thing though, that AA stated that Flights 11 and 77 weren't scheduled to fly on 9/11/2001, no airliner parts matching UA Flight 175 and AA Flt 11 were ever found at WTC, no parts from AA Flt 77 were found and/or identified at the Pentagon, and as far as I can see, no identifiable parts of UA Flt 93 were found at Shanksville, after it was shot down.
