There is not a word in there about controlled demolition.

All it says is that the trusses did not contribute significantly to the problem and neither did the fire.

It supports my "butterfly wing" theories concerning towers one, two and seven.

Here's the main argument...

that the failure of columns alone ... explains the collapses.

In other words, the columns were so badly damaged by the original impact that anything including the weight of the building itself, or the flap of a passing butteryfly's wing, could have brought it down.

Foresters run into this all the time. Trees are damaged by windstorms or by fire but don't immediately fall down. Days later, somebody walks past and a tree collapses on top of them.

There's nothing there about controlled demolition. What it does say is...

"The fact that tower one stood for 103 minutes.... and tower two for 56 minutes" after the loss of so many columns, "is a testament to the strength of the buildings and the skill of Leslie Robertson and the other engineers who designed them. I believe that few, if any, other buildings could suffer that amount of damage and not collapse immediately."
