Its either that or someone has spirited a major jetliner away and hidden it along with the passengers who held tickets for the flight. AND, (and heres the really clever part). These someones had caused a massive hole in the building and then, when no one was watching, delivered a whole pile of 757 parts that contain(apparently) fake ID numbers coincident with the missing flight's equipment. Stuff like huge piles of metal plane skin in varous sized chunks, at least 2 tires , the757 nose gear, several turbine rotors an lots of disarticulated vanes, one intact landing gear, the black box, severeal seat backs and overhead liner (identifiable but pretty chewed up), luggage chunks and clothing, blood and parts of human remains.
All these were distributed so that the responders and investigators could "find" them as if they were impacted.
Then we convinced bin LAdens son in law to admit to overhearing that bin Laden was taking credit for the Pentagon and the other three strikes.
Last time I looked , we could barely pass health care without one party trying to denut the other. I really wonder what the angle was that made all these party members make-up and work together to pull off these supposed terrorist attacks.
