My claim (no significant jolt/hesitation/collision) stands, all the videos support it, others who have measured the rate of acceleration show a straight slope (more or less), there's no reason and I have no incentive to "do the math" for you or anyone. Do it yourself if it's that important to you. My other claim also stands, that NIST committed scientific and criminal fraud also stands, the facts speak for themselves. The technical analysis exposing NIST's chicanery is incontrovertible and admitted to by NIST itself (with regard to its many "mistakes" which really amount to a vast deception). If you really believe in NIST's lies (the facts are laid out for you), that's your problem, I don't care. All the facts point to that NIST knew the fire/planes/damage induced collapse theories are fraudulent inventions designed to coverup the reality of what happened on 9/11.
