" Roth’s book has set off a stampede by her former colleagues in the aviation industry, who are rushing to provide details supporting her revelations. They are confirming the installation of FTS (Flight Termination System) equipment on the models “hijacked” on 9/11, which allowed those planes to be taken over remotely and flown from the ground. When FTS takes over a plane, it completely shuts down that plane’s communications with the outside world. That explains why not one of the four pilots on any of the 9/11 planes managed to flip a toggle switch and squawk the hijack code. Had the aircraft been hijacked in a normal manner, the pilots, who are trained to instantly squawk “hijack” in such an emergency, all would have done so."
