(18,998 posts)You said you did not need to produce any evidence just show that my evidence was not exclusive.
So if we are playing by the same rules, then I don't have to produce any evidence that there was a controlled demolition just show that your evidence for collapse from fire is not the only evidence...I did that many times now.
"I need only come up with another conclusion that uses the same set of known facts."
But that is just it...you DON"T use the same set of facts....you have ignored every last one I have posted here....and you have given us little in the way of facts...most of it is speculation....like the speculation that fire got hot enough to melt steal in an open air jet fuel fire...something that experts will tell you is really hard to do....but you ignore them.
And visual facts....like the molten steal coming out of the building...just ignore that as a fact because your eyes can lie to you...what facts have you presented that any of that is true?
The WTC was NOT and unstable building...THAT is a big fat lie.
Most of those demolition buildings are less than 40 stories...the WTC was 110 and it had core columns that were massive....there is no way you could bring that building down strait by blowing just a few of those supports
Structural System
1 and 2 World Trade Center used the so-called tube within a tube architecture, in which closely-spaced external columns form the building's perimeter walls, and a dense bundle of columns forms its core. Tall buildings have to resist primarily two kinds of forces: lateral loading (horizontal force) due mainly to the wind, and gravity loading (downward force) due to the building's weight. The tube within a tube design uses a specially reinforced perimeter wall to resist all lateral loading and some of the gravity loading, and a heavily reinforced central core to resist the bulk of the gravity loading. The floors and hat truss completed the structure, spanning the ring of space between the perimeter wall and the core, and transmitting lateral forces between those structures.
The tube within a tube architecture was relatively new at the time the Twin Towers were built, but has since been widely employed in the design of new skyscrapers. In fact most of the world's tallest buildings use it, including:
The Sears Tower (1450 ft)
The World Trade Center Towers (1350 ft)
The Standard Oil of Indiana Building (1125 ft)
The John Hancock Center (1105 ft)
