144. NIST simulation

I don't take the NIST simulation seriouly at all. Why? They won't release the code due to "national security." How did they determine it was a critical cascading 'event'? Nobody knows 'cause they wont release the coding that could tell us what variable values they used to simulated the collapse of WT7.

Here: good guy answered my question above with decent explainations. One cited was NIST. However, there's more to it than that: WT7 was the Command and Control Center for New York City responding to a catastrophe like 911. But, apparently they forgot to have the their building up to code (Fire).

So apparently a run-away toaster oven, left unattended for about an hour, could have destroyed that building. WT7 was over 50 stories tall. Yet, with minimal damage, and left to one side entirely, the very large structure collaspes into its footprint (demolition experts be damned; how do they make money anyway?).

Yet the arguments we get is that NIST calculated that a critical column failed on some-or-other floor creating an internal collapse that then leads the eyes to believe the whole builing fell at once at free fall speed.

Yeah.
