What 9-11 conspiracy theories involve the government?
Government officials for months before 9/11 admitted that they expected that there would be hijackings. They just did not expect those planes to be used as missiles against our buildings. Now Air France, some years ago continually were invaded by Algerian terrorists and their planes being hijacked, put in bulletproof doors in their cabins so that the cabins could not be penetrated by terrorists and that basically ended the hijackings of Air France planes. Now we knew before 9/11, the government admits that, we knew that hijackings were in the offing by terrorists. Why not install the same type of doors on our American airliners. It would have cost a certain amount of money that could have been passed on to the passengers and possibly prevented the 9/11 tragedy.
