@ Fire: There are a few types of missles. Some missles explode on contact, while there are others that can "rip" right through several layers of concrete before exploding. The latter type of missle usually has a timer on it (how many seconds until it explodes).
The collapsing question is easy. The planes hit the top of building, charges went off at the base and/or center, and the building fell down. By charges i mean bombs place. Thats what many Firemen and Police Officers told me the day it happened. I was cutting that day and found myself 1 or 2 city blocks away when it happened.
I doubt the firemen and police officers were all conspiracy theorists (especially b4 there was a conspiracy), so ill take their word about the charges.
Main Theory (skipping all the details): 1) 9/11 2) Patriotism 3) Anger and Hatred 4) Attack the wrong country 5) Current War in Iraq.
Obviously theres a hell of a lot more going on than 2 terrorists somehow managing to steal gigantic airplanes and going off the aircraft's current path without anyone noticing. Normally, these planes would have been shot down or "escorted" by military aircraft. It seems as though everyone was asleep that day.
Edit: I just read the post before mine. Why would someone blow up their own building? Ever heard of the Reichstag? Read about it.
Bull.
Many of the people that worked on the building have said that they were surprised they stayed up as long as they did. The heat where the planes crashed into the towers scorched to over 800 degrees celcius. This is enough to melt metal. One floor fell, and a domino effect ensued, it's not a hard concept to grasp. Because of how long the towers held together, thousands more lives were saved.

But the towers' ultimate collapse was inevitable, as the steel cores inside them reached temperatures of 800C - raising questions as to why hundreds of rescue workers were sent into the doomed buildings to their deaths.
These people rushed into the building knowing that they might not come out alive.
As for the Pentagon, it doesn't seem to be on many people's worry list, if there was really that much evidence, something would have come up by now. When the subject is widely watched, it's very hard to keep back evidence. That was seen in the Pentagon Papers incident during Vietnam and the Watergate scandal in which Richard Nixon was impeached.
About the fighter jets that should have been escorting the planes. The FBI, CIA, and airline agencies and air monitoring stations in the country before 9/11 did not share information with eachother. I've watched specials on this, fighter jets WERE set into air, but they were launched too far from New York, the planes already took a huge turn to head towards New York City, and it was unknown what their destination was.
