No, it wasn't. There was no crush up, as the Bazant paper claims there must have been.
That misses the point. All but one of the Coles experiments use "column in line" mechanisms which did not happen at WTC on 9/11. The other one also uses wrong mechanisms but a different error.
The fact that Bazant's "crush down crush up" model does not apply to WTC does not make Cole right. That is the fundamental logic error of false dichotomy that so many truthers rely on. Currently T Sz is relying on it on a couple of other forums by (allegedly) disproving Norsdenson's explanation for WTC7.
The false logic goes this way: "Someone
claims it is 'A' - you or the truther
claims it is 'B' and
proves that 'A' is wrong - then
asserts THEREFORE I am right - it is 'B' "
Childish false nonsense no matter how many times it is quoted and no matter how many debunker side arguments Cole, you or Szamboti prove to be false.
(Debunkers have probably published far more false rebuttal arguments than truthers have published reasoned claims. Think about that folks. And - before you pre-emptively shoot me - remember "Why to white sheep eat more than black sheep?"

)
"27 Debunkers got it wrong THEREFORE I am right" is utter nonsense.
You - or whoever - makes the claim bears the burden to prove that claim correct. And no matter how many opponents get rebuttal wrong the claim still needs proof.
You see what I see. You just deny it. The top mass falls all the way to the bottom, yet it does not crush up. That is what proves the Bazant paper wrong. It also is what makes the experiment different from what actually happened. The top mass is still intact in the experiment. This does not match what was observed.
There are several fatal issues for "crush down crush up"
if applied to WTC Twin Towers collapses. BUT you are still missing the point(s) which is(are) fatal to the Cole's nonsense.
