(23,872 posts)That's called a straw man argument.
You make several other unsupported assertions in this post.
"The structural steel of the ENTIRE building would have to be exposed to the flames not just on a few random floors."
Not at all. Based on professional computer modelling of WTC 7's actual structure, localized fires around Column 79 could have brought the whole structure down in just the way it fell.
"all of the load-bearing columns be broken at the same moment."
Not at all. 79 went first, taking 80 and 81 with it. Then the core columns failed, and then the perimeter columns failed. Not even the perimeter columns failed at the same time. The kink began developing in the roofline before the corner 9/11 Truth like to focus on started to fall. This was a progressive collapse, where load-bearing columns failed in rapid succession to each other.
"WTC 7 fell precipitously, at a rate closely approaching the speed of gravitational free-fall."
Gravitational free-fall is a measure of acceleration, not speed. Furthermore, that acceleration rate happened for only a couple of seconds within an 18-second collapse. There was plenty of resistance in the other 16 seconds.
"all of the features of a standard controlled demolition."
This is manifestly untrue.
