NIST claims, in the case of the towers, that the fires were an issue only when coupled with the removal of fireproofing. They even said if the fireproofing wasn't removed the buildings would still be standing.
Well the fireproofing could not have been removed where they said it was, due to the debris field velocity and position, so here we have another impossibility.

What makes it look like a giant hole is from the wings, but they couldn't get very far from the exterior they impacted.
That would be true if you ignored the mass of the fuel. If I remember correctly, even the Purdue team was surprised by it's effect.![]()

Thanks for answering,
So what percentage of the width of the building would need to be taken out to make the building unstable.

First, the fuel has to hit structural members as a mass with high velocity to take them out. The fuel that did make it past the exterior would have been highly dispersed.
In addition, there were 10,000 gallons on each plane, which is equivalent to a volume of 1,333 ft^3. If 50% or 667 ft^3 made it past the exterior then that would be like a 9 foot cubed item. If you add it to the fuselage, engines, and landing gear you have a total of 15% of the cross section of just one floor. The fuel was also mostly in the wings which impacted over about six separate floors.
I don't believe the fuel could have done any damage to structural items past the exterior and even when combining it with the other items they make up a very small percentage of the cross sectional area impacted.
The impacts actually did very little to the overall structure. It was the effect of the wings on the exterior of the impacted face that made it look like it was much greater than it was in reality.

You don't get it. If complete failure, in the manner of the the tower collapses, was possible, it could been duplicated in a computer simulation. Individual components of the support structure could be programmed to fail to determine how the building would react. Fire did not have to be factored in, only the weakening and failures of the support structure which could have been the result of fire and the crashes need to be programmed.
Correct
I don't get it. Explain what you are trying to say without putting the word could in it.

Can you explain what the impossibility is, exactly?Well the fireproofing could not have been removed where they said it was, due to the debris field velocity and position, so here we have another impossibility.
Yet NIST's analysis, independently of how accurately represented the impact angle, shows otherwise: in their analysis the buildings collapse with far less than 50% columns. Care to explain that discrepancy?Well John Skilling said you could remove one face and the corners and still be able to take a 100 mph wind.
I believe you would need to take out about 50% of the columns along with fires to actually effect a collapse.

You are not implying by innuendo that the collapses were impossible, right?

The impossibility is that the debris was moving far too slowly and was at a much lower level than the 98th floor trusses, so it could not have removed the fireproofing there.
The NIST analysis just implies collapse after the south wall was allegedly pulled inward by the trusses. Do you care to explain how the failure of the south wall would effect a complete collapse, because NIST did not explain it?
so it could not have removed the fireproofing there.
