"This footage was posted to video sharing network Veoh.com on November 1, 2008. No information or data accompanies the video and there is no sound on the original file. The video was posted... by “GldBr,” a user with no other videos or information."The first two minutes of this video are of Building 7. Remember, this is the building that wasn't hit by any planes. Its fall was officially attributed I think to fires in the basement and collateral damage from debris hitting it when the twin towers collapsed.
Many observers have noted that the building drops in free fall. It doesn't successively pancake one floor onto the next - it freefalls to the ground unimpeded.
What's interesting in this view is at the 0:20 mark - before the building starts to collapse - seven vertically aligned windows near the right front corner appear to blow out. I'm not saying this is a controlled demolition. But it does illustrate the way a controlled demolition is achieved - by instantaneously blowing out the support columns.
The second part of the embedded video shows apparently new footage of the North Tower of the twin towers; it's interesting that the central elevator shafts are still standing as the cement dust cascades down, but that doesn't prove anything.
In no way does this video show the windows being blown out. The windows break from wall distortion when the outside wall is pulled inward by the collapsing floors.
ReplyDeleteWTC 7 a high-rise office building met all New York City codes and was not hit by any planes and was destroyed by a fire in ordinary combustible furnishings. You may say it’s highly unreasonable to believe that 4 steel constructed high-rise buildings collapsed from fire in one day? Well they all had one thing in common; Long Span steel composite floors with connections not designed for thermal effects. In the design of these buildings the removal of interior columns interfering with exterior views and office layout was attained by long span floors which are used in many existing office high-rises. The use of long floor spans along with the 1968 building code relaxation lowering the fireproofing requirements have apparently created a condition that with large fires in these buildings could lead to total collapse. Long span steel beams have a magnified response to heat. They expand a longer distance than short span beams and they still have their full strength in the beginning of the expansion. NIST computer studies show that this strength while the beam is elongating can shear off the bolts connecting the beams to the columns or girders as the restrained beams expand. This strength can also crack the concrete slab at the shear studs and buckle the beam itself as differential compression builds up during expansion.
A buckled or bowing long span (over 40 feet) beam can impart large tension forces on the connections especially when the deflected beam begins to shrink as it cools. Bowing occurs when the bottom flange of a steel beam expands faster than the top flange. The fireproofing insulation thickness schedules in the Building Code were developed for the short span floors which were used in the older buildings and this insulation defended against weakness in the steel beams rather than expansion which apparently was not a problem in the shorter spans. Steel weakening occurs later at higher temperatures 1100deg. F (about 600 deg. C). Low temperature expansion effects occur earlier as the steel is first heated at temperatures below 400 deg. C and long span expansion effects have not yet been compensated for in the codes. This deficiency in high-rise office buildings using long span flooring systems, is a new discovery uncovered by the study of the collapse of the Twin Towers and Buildings 5 and 7 and was first illuminated by the engineering computer studies.
That is certainly possible. I would note, however, that none of the 200+ windows facing the camera break in that manner, either when the floors are supposedly collapsing, or when the building is obviously collapsing in free fall. Curious how it's only those seven in a vertical row by the corner support pillars...
ReplyDeleteAnother profound revelation by Arthur. Of course it's a copy/paste that is seen on articals all over the tubes, where this video is shown. This tells me that somebody wants the video to go away. Hmm, I've already posted it, but it has been a while. Maybe I'll post it again...G:
ReplyDeleteHere's a link to a conversation with Arthur...G:

Thanks. And here's some more grist for the mill -

Exactly how did whoever-it-was smuggle the miles of wiring and the tons of explosive into the building, pre-stress the structural components (normally requiring several days if not weeks of very noisy drilling) and set up the ignition desk which was going to 'demolish' the building in this fashion with sequential controlled explosions? All without anyone working in WTC 7 noticing? How did 'they' know in advance that WTC 7 was going to be damaged at all, that there would be sufficient damage to it - no airplane impacts, after all - so that a planned demolition would not be so totally obvious as to blow the whole scheme into the open? What previous personal experience of demolition makes you think that this isn't exactly how such a building, damaged in exactly the way it was, will collapse?
