I think most all of us can agree with the following statements:
1) The best way to scientifically determine why each of the 3 towers originally gave way would be to collect and forensically study all of the columns which in all probability gave way first.
2) If all columns within the collapse initiation zones cannot be collected, an acceptable alternative would be to collect and forensically study more than enough samples to form a representative collection of columns from the collapse initiation zones.
3) During the careful examination of these collections we would look for evidence to tell us:
a) To what temperatures were these columns subject?
b) To what extent fireproofing was damaged and whether this damaged fireproofing was what actually lead to collapse initiation.
c) Just where and how the columns in the collapse initiation zone first gave.
This, if possible, would have been the natural way to proceed and apply the scientific method.
So how many core column samples from the collapse initiation zones did NIST examine and why? They tell us in the following quote:
Their entire forensic collection consisted of only 4 core columns. They admit that such a scant collection cannot give a realistic sense of what temperatures were actually experienced inside the core. And as for a practical sense of the loss of fireproofing and how and where the first columns failed, what can you learn a sample consisting of less than 1% of the total?
And how many column sections were saved for analysis from WTC 7? None that I know of.
I agree that the sceintific method could have told us all we needed to know. But from the POV of the NIST report, that which we can pretty much all agree would have been the best evidence to work with was destroyed before NIST could examine it.
It would have been science were the key evidence not trashed before NIST could examine it.
Having the key physical evidence trashed, it is a little late to preach strict adherence to the scientific method.
The science has been done and your agenda-driven fantasy requires you to reject the conclusions that have been reached. That is the target the OP aims at.
