Claiming something and proving it are two different things.
If they won't even talk about how steel had to be distributed in a structure that supported itself for 25 years I am not about to just BELIEVE.
In the places the structure was distributed as designed it held up just fine, even while it was already collapsing in other places;
why discuss it in more detail than NIST NCSTAR 1-1?
What happend when things got redistributed by airliner is discussed in NIST NCSTAR 1-2 and NIST NCSTAR 1-6.
the ‚distribution‘ in the downward progressing collapse zone looked so chaotic it’s beyond discussion but obviously not fit for supporting anything.
A big jumble of steel and concrete settling (well, trying to) on a self supporting structure that simply wasn’t designed to take up that kind of load.
are you really surprised that it didn’t hold?
