planes hit towers 1 & 2 but they were actually brought down by explosives (super thermite) which was found all over ground zero. flight 93 was shot down in pennsylvania. you can find the video of donald rumsfeld slipping up and stating that it was shot down. not all levels of the government/military were involved in the conspiracy so they decided to take it down. flight 93's target was building #7. the explosives were already in place so they decided to go ahead and "pull it" and blame it on debris. a missile hit the pentagon. if you see footage of the building soon after it happened the top of the building had not fallen yet and there was no way possible that a plane fit through the hole that was made. theres a strong possibility that the planes were being controlled by remote. our country have many unmanned planes "drones" in the middle east and here in the US that patrol our borders. dont think your government is capable of such a thing then just google "abc operation northwoods" or " george washington university operation northwoods" PEACE !
