WTC7 report not cutting it with the 'folks

NIST's WTC7 collapse models: some observations - Arie X - 08.30.2008

A few days ago I posted a graphic from NIST's latest WTC7 report that depicts the exterior buckling after global collapse initiation. In no way does it resemble how the structure actually looks when it imploded. I had not noticed that this was the model for the scenario without debris impact damage. You see, NIST actually has models for the scenario without debris impact damage and for the scenario with their best estimated impact damage (the damage to the south side). They conclude that the building would also have collapsed without any impact damage.

So I checked the report for their modeling of the exterior buckling with the best estimated impact damage; the model of what actually happened. It's there but there is something missing: the top 23 floors are not shown and the north side is not shown; the side that can actually be seen in the videos and photographs of the collapse.

It would be hard to imagine that the scenario with the asymmetrical damage to the south side would leave the top 23 floors (which are not shown) looking any better than the scenario without damage.Videos show that WTC7's walls remained straight during most of its collapse. Their model is simply not showing what actually happened, and it looks like they are trying to hide it by not showing the top 23 floors and the north side.
