It wasn't 'just a hole in the top'. When those planes crashed into the buildings, they severed several of the supports that held the exterior walls as well as crashing into the central support columns and destroying several inches of flame retardant insulation around each of them. That was followed by the buildings burning, uncontrolled, for nearly an hour, which further weakened the supports that were already under more stress than they were designed to withstand since a portion of the support system (the exterior walls) had been destroyed. A CONVENTIONALLY built skyscraper would probably not have collapsed, but since the towers were built differently, comparing the stresses that wouldn't cause this to a conventional building is an invalid argument. The jet fuel also didn't burn up in 5 seconds. It flooded down chases like stairwells and elevator shafts and allowed fires to spread from the initial point of impact to other combustible materials throughout the buildings.....which is the cause of the sounds of 'explosions' people reported in interviews after the events.
The buildings did not fall in the 'exact same way' as a controlled demolition. Nor did they fall 'into their own footprint'. Nor did they fall at 'free-fall speed'. All those claims have been debunked by Popular Mechanics as well as structural/Civil/mechanical & explosives engineers worldwide. Sure, some doubt the 'official' story, but that doesn't mean that the 'official' story is false. Also, those who doubt it have much less evidence to support their version of events. Matter of fact, the vast majority of their arguments stem from conjecture rather than evidence.
Larry Silverstein is a 'red herring' for conspiracy theorists as well as certain offices located in the buildings. Lots of people weren't in the buildings that day. Does that mean they, too, were part of the conspiracy?
Bottom-line: Claiming the event was orchestrated by our own government assumes those who dislike our country aren't resourceful or intelligent enough to pull it off under their own power.
