The object that hit the pentagon was a US NAVY A3-Skywarrior (with a bottom-mounted thermoberic missile) which was retired in 1991 and converted to a drone using the FTS wargame safeguard technology (remote control/detonation), which was launch from the US NAVY carrier the USS George Washington which was off the East Coast just South of Miami, Florida near the entrance to the Gulf of Mexico participating in a wargame (Vigilant Guardian), which impacted the pentagon at the same time as they set off internal explosives which were planted in the walls instead of kevlar in the targeted areas during a recent renovation to the Office of Naval Intelligence inside wedge 1 of the pentagon (as well as the exterior walls of the west face of wedge 1), renovations which were finished 1 day prior to 911 (the same day Rumsfeld announced the missing 2.3 trillion). What you didn't know the NAVY had such a big roll in 9/11?
