"A major piece of evidence in the WTC 7 collapse is the fact that WTC 7 underwent free-fall acceleration for a period of at least 2.25 seconds.[3] A free-falling building means there is no supporting structure whatsoever below to slow the building’s fall. The NIST theory does not explain this astounding fact.
"However, if their theory is to believed, the 2.25 seconds of free fall must have resulted from near-simultaneous buckling and breaking of the 58 perimeter columns and most of the 25 core columns over eight stories.
"The only evidence NIST provides to support their theory is in the form of a computer model.
"While it could possibly be argued that the model does show some buckling occurring over eight stories, it most certainly does not show a period of free-fall. So NIST’s theory has absolutely no scientific evidence whatsoever for the fact of free-fall. In other words the NIST theory cannot explain key empirical data."
