allie, something to ponder:  Buildings 1 and 2 were struck by aircraft at different angles of attack and at different levels, yet they both imploded into their footprints in identical fashion.  Buildings 3 and 4 burned for hours, yet their superstructures remained intact.  Building 7, which was not struck by aircraft, and which had small fires burning on two floors only, which the NYFD was preparing to extinguish, imploded into its own footprint.  How is any of this to be explained, and why has no attempt been made?
