Reply #14: WTC7

[blackowl]

I'm not sure why you take issue, friend. Silverstein already admitted demolishing WTC7.

"I remember getting a call from the, er, fire department commander, telling me that they were not sure they were gonna be able to contain the fire, and I said, "We've had such terrible loss of life, maybe the smartest thing to do is pull it. And they made that decision to pull and we watched the building collapse."

So take it up with Silverstein. Or the laws of physics. Or common sense. Because buildings don't simply collapse into tidy piles of rubble when small fires break out. If they did, there would be no need for demolition companies. You could simply drop a match in a waste-paper basket and watch your target structure disintegrate.

Regarding the other two towers, well, here’s what the site had to say about the film:

NOVA/Eagar Use Deceptive Techniques
Images and movies misrepresent the towers as flimsy structures just waiting to pancake:
· animation:
o Omits cross-trusses, which would spoil zipper effect.
o Implies floors rested on trusses. In fact, trusses were bolted to steel floor pans every few inches.
· structural schematic:
o Core depicted as horizontal slabs instead of vertical columns.
o Spandrell plates linking perimeter columns are omitted.
· plane approaching:
o Plane is size of 747, over twice size of 767
o Horizontal ribs replace vertical columns.
The Truss Failure Theory According to FEMA
FEMA's BPAT gave the truss failure theory the official stamp of legitimacy in their report.

tall freestanding columns??We see only short freefalling column fragments.
They say the perimeter and core columns would self-destruct if the floor diaphragms collapsed:
As the floors collapsed, this left tall freestanding portions of the exterior wall and possibly central core columns. As the unsupported height of these freestanding exterior wall elements increased, they buckled at the bolted column splice connections, and also collapsed.
The columns were not freestanding:
· The perimeter columns were grids with horizontal spandrell plates linking the columns.
· The core structures were lattices, densely cross-braced.
Note legalistic CYA language possibly central core columns:
Engineers knew floor failures would not destroy core structures.
FEMA's core fraud became accepted fact.
The New York Times reported in May 2004:
The interior core of the buildings was a hollow steel shaft, in which elevators and stairwells were grouped.

The Truss Failure Theory is a Diversion
It avoids the glaring deficiencies of the column failure theory, but likewise doesn't begin to explain total collapse.
· Prerequisites didn't exist.
o Neither tower's fires covered even one entire floor.
o Eager's zipper scenario is impossible given the cross-trussing.
· Domino-effect floor failures were not possible.
o The fall of a floor would easily be absorbed by the floor below.
o Some floors must have had large I-beams. Otherwise the building's tube-within-a-tube design made no sense.

The towers collapsed straight down.
Discounting demolition, they followed the path of most resistance.
