You have to visit the references in the links I provide in my article
http://heiwaco.tripod.com/nist7.htm . Evidently sol gel nanothermite exists as development of same is paid for by US tax payers. I do not refer to thermite cutter charges in my article, so pls do not suggest I allege anything of that sort.
I just try to imagine what could produce free fall of the upper, visible part/mass of WTC7 during 2.25 seconds, i.e. that all supports of it are removed allowing free fall for 2.25 seconds, i.e. the whole upper part/mass of WTC7 is dropping or being pulled by gravity without anything stopping it for 2.25 seconds, i.e. anything below the upper part/mass must have been removed! Fast! Instantanesously! It evaporated. How could it be done?
And why does NIST suggest in its report that this upper part/mass deforms while dropping? Gravity force does not produce any deformations at free fall! All the gravity force does is to produce free fall!
