<------ My doggie is growling at you!!!
Regarding WTC7:
In 2006 NIST said Free Fall collapse was impossible cuz it would require the absence of resistance of the interior/exterior columns.
In 2008 NIST said Free Fall occurred for a period of over 2 seconds or for the building to fall 105'.
The videos existed both in 2006 and 2008.
The building came down as depicted in the videos.
Why would NIST not consider the obvious in 2006?
When the building engaged resistance after some seconds of Free Fall it tilted to the South as a bloc and fell apart there into a heap [a few videos show this action].
A collapse caused by fire alone or fire and damage [NIST says damage did not play a part] would have resulted in a sequential collapse of the columns and this would have been seen. The building would have fallen apart and the bits would have followed the path of least resistance toward the ground.
NIST did not look for evidence of explosives. Their spokesperson indicated that it made no sense to look for what was not there. IOW, they had no reason to look so they didn't. Their spoke person indicated that he knew of no credible statements of Molten anything anywhere or any proof of it... I'm not sure if he means he heard the evidence provided by fire fighters, police, demolition folks on the scene to clear the debris, photos of molten stuff and FIMA's comments plus other evidence available.
Any action regarding the exterior columns would be reflected in the granite and windows that made up the facade... no one rejects this to my knowledge.
The issue is and will continue to be the manner in which a fire only caused thermal expansion collapse of ALL the structure for 105' to enable the upper 105' to fall at Free Fall Acceleration can occur. IF someone has special insight into how to enable this thermal expansion to occur symmetrically and immediately to 105' of structural beams, columns, trusses and what ever else there is in there including the stair wells and etc., kindly send it to NIST so they might insert it into their SIM and have the SIM depict the video from start to finish...
Don't send them info regarding the big smoke and fires on one face... that won't cause a symmetrical failure cuz they reject that.
