2013年11月20日 · Something I rarely to never see discussed, here or elsewhere, is WTC6, an adjacent building which suffered some extreme and very strange damage. As you can see in the bottom-left corner of this image, building 6 has formed something of a crater, its central mass missing in a 'pit' that descends right to the ground-level.

2012年9月10日 · Also there is a church and a bank building that was right beside WTC 2 and they did not collapse. So based on what I have read on how the fires caused WTC buildings to collapse, the building WTC 6 that stood between WTC 7 and WTC 1, would have collapsed before WTC 7 along with other buildings that are within a closer proximity, yet they never did.

2021年10月23日 · Is that the restaurant on top, I don't think those are WTC load bearing columns, save the needed strength to survive hurricanes, high winds, hail, and big birds. It appears those windows are double wide compared to the windows in the tower where the shell holds up nearly half the gravity weight of the WTC.

2019年9月3日 · World Trade Center Building 7 (WTC 7) — a 47-story building that suffered a total collapse at 5:20 PM on September 11, 2001, following the horrible events of that morning. The objective of the study was threefold: (1) Examine the structural response of WTC 7

2019年3月9日 · The 1st animation was generated on a graphics engine similar to PS/2 title "Mercenary". The second and third are CONCRETE structures, the WTC was A36 structural steel which has a tensile strength of 89.000psi, basically it would take a square inch of material per foot of wingspan to stop such a hollow aluminum object moving 500fps.

2018年1月27日 · EDIT: Just some notes to help people clarify the perspective. This photo is taken from an angle very similar to that of the photo Mick last posted above, except that in this photo the Brookfield Plaza building obscures the northern outside wall of WTC 1 and the remains of WTC 6.

2013年11月20日 · There was clearly smoke from a number of buildings and remains of buildings. i.e. remains of 1 & 2 and also 5 & 6 which were all behind 7. The smoke can clearly be seen blowing away from 6 across to 5 & mixing with smoke from 7 …

2014年5月3日 · sections of the building falling outward and impacting WTC buildings 6 and 7. This was not a glancing blow from extraneous material, rather thousands of tons of steel girders falling directly into the building from hundreds of feet above. WTC 7 sustained significant impact damage to its southwest corner up to the 18-20 th floor, or a little less

2013年1月22日 · At around 6.40 you can see wtc 6 burning much more violently and that did not collapse. Click to expand... At 5.00 i see a lot of heavy black smoke pouring out of WTC7 and near 6.40 i see heavy flames erupting out windows on the east side of WTC7, the end of the building where the collapse originated.

2013年10月6日 · I take it we are supposed to believe there is special significance to WTC 7? It isn't the only building which had a structural failure due to fire: "The major fire-induced collapse that occurred in WTC 5 involved the portion of the building that had Gerber framing (girder stubs welded to columns, and simply supported central girder spans with shear connections to the ends of the stubs (Figure ...
