Creative Speculation

NIST's models show the perimeter columns folding up like the walls of a wet paper bag--even after the floors had broken free. Had the perimeter columns folded up, the curtain wall elements would have popped off and fallen to the ground.

The fact that NIST's models did not show the curtain wall is meaningless unless you are going to claim that a) the floors pulled loose from the perimeter columns, which remained standing for 600 feet without distorting (despite the presence of a breeze from the NW) or b) the perimeter columns folded up as NIST's models did, and the curtain wall stood straight and unperturbed. Do you think that a curtain wall that hangs from a steel structure is going to stand 600 feet tall after that steel structure is removed? If not, what is your point?

I don't need to challenge the physics of the simulation. I need only point out that it does not even resemble reality. I don't need a hypothesis. I need only point out the obvious deficits in NIST's analysis and call for new, complete, honest investigations.

Most of the core columns were hollow. You don't know what you're talking about.

Do you have audio recording the sound of 47 concrete floors falling or not? I'm not willing to watch 8 minutes of video trying to determine whether you have a point or not.

You have not demonstrated that a cracking sound is an unavoidable presence in controlled demolitions. That's like claiming that slaying is always done through lethal injection or firing squads or hanging, and thus someone could not have been slain with the jawbone of an ass.
