Report page 108, PDF page 120 shows UAF simulation against Chandler’s video measurements. The graph is a bit crowded, but from t=~0.3 to t=~0.8 you can see uniform velocity of about 1 metre per second. No acceleration, uniform velocity. Can anyone please suggest ways that this might be consistent with collapse initiation by explosives?

In all, I am unimpressed with this report. 90% of it consists of claims of what couldn’t have happened. There are an infinite number of ways anything can break, yet only a handful of failure scenarios were modelled. It confuses free-fall with g, and shouldn’t be claiming any free-fall for the shell of the building because the report itself requires that the shell remain connected to the core.
I think that the report’s emphasis upon simulation is premature. It would have been more useful to concentrate upon data gathering and measurement, establishing limits of accuracy of initial conditions, and then crowd-source multiple simulation scenarios in the manner of Seti At Home or Folding At Home.
On the plus side it does show what a pig’s ear of a building WTC7 was. It confirms that column loads were wildly uneven, with column 79 carrying way more than most others, nearly four times the load of column 65. Further, this report establishes that global collapse of the building would have ensued from the failure of just six core columns.

To the Truthers, I ask this; for what reason would the conspiracy have pre-rigged this building for nearly symmetrical bottom-up collapse?
