Donuel, most of your statements are demonstratively wrong. and have been demonstrated to be wrong.
Here's just one:
There was no Thermite at ground zero. This compound, that you seem to think is an explosive, is used to produce an exothermic reaction. It builds great heat, but little outward gas pressure. It is used to bore through metals over time, as well as in a form of welding.
Do you really think that steel heated to over 2,000F over time by burning av-gas will not soften? Bin Laden counted on it. He said that he was expecting that the upper floors would collapse. The more complete destruction from the inertia of material from above was just an added bonus for him.
Look at pictures of steel being worked at a mill for a reference point. Now take that softened steel and place a gazillion pounds of building on it. What happens? I bet you know.
