By definition, isn't "free fall" only possible with zero resistance underneath it?
With nothing slowing the path of descent?
Exact free fall is only possible with zero resistance. The NIST only had videos to measure acceleration, and that is not an excact science or means of measurement, so it wasn't "exact" free fall, but close.
With enough weight bearing down on lower structures, especailly with many of those internal structures already compromized due to fires and previous internal collapses before the main collapse, there wasn't much resistance to the overall collapse.
Some will pretend the dynamic loads are no greater than the normal static loads and that every column would have to be cut simultaniously in order to reach free fall acceleration. They ignore video and audio evidence that these explosions never happened.
