so, does anyone actually buy it, that is the excuse that WTC7 fell as it did, because for 8 stories of structure, the resistance was uniformly removed because of "columns buckling and losing their capacity to support" and this was the result of chaotic fires & damage to the south side of the building caused by rubble thrown off by the collapsing towers.
(?) The NIST offers up lame excuses!
To address the fires bit, have you ever been to an amusement park where there is supposed to be a building being consumed by fire, but its all effects, yes, there are flames & heat, but its all controlled and there is no danger of anything actually burning down. The only indication of fire in WTC7 is by way of seeing what is apparent in the flames from broken windows, whatever is really going on inside the building is out of sight and therefore unknown.
