In its draft report, released in August 2008, NIST attempted to cover up evidence that WTC7 fell at freefall, but the coverup was transparent. In its final report, released in November 2008, NIST finally acknowledged freefall, but couched it in a bizarre framework that continues to deny its clear significance.
The clear significance of a period of freefall collapse indicates absolutely no resistance was being offered by the building structure. This is obviously impossible in terms of the fire induced collapse model since, during the collapse, undamaged portions of the structure would slow the fall rate. The resistance offered here should be more than that of air alone. Steel columns, even ones that might be buckling, would still resist the fall.
However, in the case of the WTC7 building, the massive structural columns appear to have vanished into thin air for at least 2 and a half seconds !
Of course the most reasonable explanation to account for this incredible phenomena is the use of an explosive agent that can remove resistance almost instantaneously. In this regard we have abundant physical evidence showing that this is exactly what occurred in the form of the molten steel and the thermate products that were discovered in the rubble subsequent the collapse. Without doubt, Building 7 WAS brought down using explosives.
An earlier video excellently and more fully explains the significance of the freefall collapse, see below:
Readers should note that deliberately covering up a crime is, in itself, a crime.
