That happens to be the very argument that I had with Cters. That the overall collapse would require more computer modeling that is currently available.
But certain aspects of the collapse might give indications as to what went on after and why the early air data, is confusing.
One thing I found out in studying the chemical composition of light weight concrete with steel reinforcements is that Calcium Chloride is replaced with outer Accelerators and watering agents, such as sulfates, Calcium Nitrate, Calcium ThioSulfate, and even Gypsum.
I took some steel exposed it for a few days to Calcium Sulfate fertilizer in a free Oxygen starved Environment, and then exposed it to air. The result was a blue sulfur and steel flame. Calcium thiosulfate was all I had to test though, I use it on my Straw Berries.
Calcium Chloride is simply to corrosive to have been used on reinforced steel in light weight concrete.
Now you can call me a loon, but I do not know what the effects would be in the towers, or if it was even applied when I contacted people to find out I was told to refer to the NIST report, I could find nothing on the accelerators used in the concrete.
I simply can not find any more information on it.
One wetting agent is,

I can find no data on the chemical composition of the concrete, and it is more complex then I first believed.
If I am wrong then that is OK, I am happy with NIST, as the best answer so far, but when your looking objectively and you see data that remains curious and you wonder what the explanation is, and you can not find out then how can your curiosity be satisfied.
YOU KNOW I am not a Cter, just seeking explanations to mysteries still left unsolved.
I can not ignore a great unexplored mystery, Because as Apollo20 has said, I do think outside the box.
I could never afford the box big enough for me and my chainsaws, and have you ever tried to use a gas saw inside a box it does not work, both you and the saw require oxygen.
I live in a physical universe where A+B=C the air Data is C I am just looking for What A+B represent.
