2.25 seconds of free fall during its collapse. Steel offers a measurable, minimum amount of resistance to collapse. WTC 7's dead loads were its own components, i.e. the building itself. The only circumstances that could explain free fall of this building are a) controlled explosives or b) WTC 7's own components being so overwhelming to its support structure that it collapsed in such a fashion as to be immeasurably slower than free fall acceleration. I assume, since you've clearly argued this, and allegedly debunked it, that you were able to demonstrate how WTC 7's own dead load produced free fall results, i.e. that WTC 7 was the most poorly-constructed steel-framed high rise in history.
