"But...you just said that he already answered the question. If there is no valid answer, then his answer is not valid. And how can he say it didn't look like it was supposed to if there's nothing to compare it to?"
The OP;
"Prove to me that the collapses did not look right...prove to me that a fire initiated structural failure collapse would look any different from what happened."
Yes the OP was intended as a trap.
So what I did was
respond to the OP in the only manner I saw possible.
There are no
proven examples of modern steel-structured office buildings being felled by fire.
But, just because we do not know what an unprecedented collapse would look like,
does not mean that we cannot make some reasonable assumptions about what it CANNOT LOOK LIKE.
Thanks to the controlled demolition industry, we do know what
other steel-structured building collapses look like using CD technology.
And there is a library of information available about the destructive behavior of fire.
There are many examples of large non-steel-structured buildings destroyed by fire.
Regardless of the uniqueness of the WTC building designs (not truly unique, I worked in an office tower in Toronto of similar construction), the contents of the floors can be validly compared to the floor contents of other buildings.
Perhaps in the case of those non-steel-structured buildings which completely collapsed from fire, you could argue their plastic content was lower.
In order to believe that WTC1, WTC2 and WTC7 were high speed total collapses triggered by the ultimate effects of fire, it is necessary to accept that fire was able to far out perform controlled demolition technology.
WTC2 is of particular interest, in that 56 minutes after aircraft impact, it was supposedly induced by fire to perform a high speed collapse.
56 minutes for burning office furnishings to supposedly make the structural steel totally and rapidly fail.
Why I find this especially interesting, is that there was a long period where a heavy flow of molten steel was falling from a critical corner where the collapse was initiated.
10-20 seconds after this flow of molten steel ceased, the collapse began.
Coincidence?
I do not believe so.
The result of thermite and not ordinary fire?
Yes.
