The official story is that a 757 airliner piloted by an arab terrorist slammed into the front of the building. We all saw the hole, so what's the problem?
Well to start with, the hole after the roof colapsed was only about 65 feet wide (there are pictures and video before the roof fell and the hole was considerably smaller than that) The wing span of a 757 is 124 feet 10 inches. Just look at the picture. Notice that the windows to the right and left of the hole are not broken? What about the holes that the engines would have left? These are not minor details. A plane with a 124 foot wing span does not slam into a building and leave a 65 foot hole. It's physically impossible.
