The building came down at freefall for 2 secs after

the left side collapsed in the NIST model. There was still 2/3's of the structure on the right side intact. That 2/3's would have prevented freefall. I still maintain that freefall cannot occur without a simultaneous and complete shearing of every column at the exact same moment leaving only air to resist the collapse.
