November 11, 2002: It is revealed that while the government didn't ban box cutters, the airlines' own rules did. It had been widely reported the hijackers used box cutters because they were legal. It now appears pepper spray was also banned, and like box cutters, should have been confiscated. There is evidence the hijackers used pepper spray as well (see July 18, 2002). It has been reported that nine of the hijackers were given special security screenings on 9/11, and six of those had their bags checked for weapons (see March 2, 2002 (B)). How did the hijackers get their weapons on board the airplanes?
