"WTC 1, 2, & 7 were controlled demolition, that's a fact. Think about this ...
1) Horizontal ejections of multi-ton steel sections up to 600 ft at 60 mph
2) Asymmetrical damage resulting in symmetrical "collapse"
3) "Collapse" at near free-fall acceleration
4) Positive identification of Nano-Thermite
5) Tons of molten iron under all three structures
6) Temperatures well above those possible in a hydrocarbon fire"
