Penultimate Amazing
Except it does. The 'kink' develops through both interior and exterior(at least on the north face) consistent with the location of first visible failure, the collapsing of the east penthouse. Then the structure east and west of that line also collapse.No I don't agree with NIST. They say the interior of WTC 7 collapsed on the east side first going north to south and then east to west naturally. If that were true then the east side exterior would have started coming down when the interior went down on that side. It doesn't.
The rooftop structure failure also indicates an east to west failure as the western rooftop structures collapse after the east mechanical penthouse.
Then there is the definite difference in construction east of the kink than west of it. To the west , the north side of the structure relies upon the cantilever truss system whereas to the east no such system is employed.
I fail to see how you would justify that thought given that the east penthouse failure is quickly followed by the western rooftop structures also falling, and the quite obvious fact that the first exterior failure is the 'kink' which lines up with the east penthouse, and indeed col 79's location.I think the east side penthouse drop was a somewhat local (at the top only) event,
Why is it that you cannot see that a very specific line of the exterior failed first?, and that the full core was cut over eight stories lower in the building at one time and that is what caused the symmetric collapse of the exterior.
WOW! So after years of being told that the only way to achieve free fall acceleration is for there to be absolutely no columns intact you now tell us that this only applies to interior columns.There is no need to cut the exterior when the core will pull it inward over eight stories making its resistance insignificant.
