The NIST Animation Model:
NIST's THEORY is a claim that the collapse of WTC7 was initiated by the failure of one vertical column (79) which was located in one corner of the building. That due to thermal expansion from intense heat, several horizontal columns pushed column 79 off its seat, causing it to fail and that a "rapid" succession of columns progressively failed, leading to the total collapse of WTC7. NIST also claims that following the penthouse collapse, allegedly due to the failure of column 79, WTC7 dropped at free fall speed for the first 100 feet (8 stories) for 2.25 seconds. Shyam Sunder announced that this collapse cause and sequence was "obvious" a few years after he said that NIST could not get a handle on what caused WTC7 to collapse.
The above model obviously fails to demonstrate any of this. NIST also refused a FIOA request for any of the material used in compiling the program model citing that its public release would "jeopardize public safety". The animation seems to purport that the collapse was initiated at some lower floor, showing some sort of bottom to top domino effect that brought the penthouse down and that the collapse actually started on one side in the interior of the building that no one could see (the surrounding walls seem stationary at first), then the interior collapse seems to drag down the rest of the interior of the building, eventually bringing the exterior walls inward (the animation shows a severe wedge beginning at the center the roof line and opening widely down). There does not seem to be a link between the column 79 failure and the progressive column failures during the collapse and there is nothing in the animation that matches the description of the free fall at what NIST labels "stage 2". And the animation abruptly stops at the first few moments of the collapse, the rest of the collapse (the majority) is left up to everyone's imagination.
Then there's the REALITY that fails to match the animation:
The entire sequence of events, according to NIST, was strictly due to fire and NO OTHER contributing factors. NIST specifically claims that the debris from the collapse of the North Tower that damaged WTC7 did not contribute to its collapse other than starting the fire(s).
