How can you even assume it was fake?
Exactly, THERE WAS NOT PLANES?
Oh ok, so where did all the passengers of the missing flights go, what did we see that was just as big, the same shape and the same sound of plane that flew into the towers?
Are you suggesting the US has some kind of super projector? Heres something for you, get in your car and try to drive through about 5 walls of reinforced concrete, see how far you get, not even through the first one is my guess, thats kind of what these planes faced, which would be why theres no hole in the other side, they just smashed through and broke up on impact, planes arnt made like tanks, they are very nimble when it comes to things hitting them.
