/07/11 · keshavpathak The 9/11 WTC Collapses: An Audio-Video Analysis. „Never before in history has a steel high rise building collapsed simply because of fire. On 9/11, by coincidence, three such buildings collapsed in ten to fifteen seconds, almost freefall speed. In other words, if you dropped a brick from the top of the World Trade Center it would have taken.

Videos of the South Tower Destruction video frames duration description mpeg sequence matrix South Tower collapse from the east This second NBC video shows the upper 40 stories of both towers, starting just as the top of the South Tower begins to lean. The video was aired by NBC approximately seven minutes after the event.
After the videographer turns around and starts to run, he points the camera backward, recording the encroachment of the monster dust cloud. The clip runs right up to the point that it overtakes him. The top of the South Tower starts to lean at about 11 seconds. The videographer looks up to capture the explosion about two seconds later.

Edit: I refer to the viscoelastic dampers as plastic, but that was a flippant thing to say; they were actually steel with a viscoelastic material included. And to prove I have forgotten more than I can remember, I was also wrong about the truss sizes. The short trusses were 35 feet long, not 40 feet long.
I do just that in this two-hour conversation with Don Fox, Joe Olson and Jim Fetzer, all of whom are big nuke advocates. What I said that was so stupid was that the viscoelastic dampers were not steel, but plastic and would therefore have been vaporized by a nuke before the steel, an easily disproved statement, and one that I know better than to say. To be honest I have noticed that when I start to feel like a smarty pants, I tend to say dumb stuff.
One of the people who pointed out my mistakes has been constructing his own models, only his are architecturally accurate, whereas mine are only useful to the layman. I was humbled by the detail of his work, as well as the knowledge he had of the tower construction as compared to mine, but this very smart man could not explain why the spandrels above the lobby area had no sign of floor material whatsoever, as compared to the lobby ceiling material; instead he would point to the details of the construction, and mock me for even suggesting they were dismantled.
He then explained that the jets were real and that it is ludicrous to think that missiles were launched in broad daylight. Like Jim, Joe and Don, this guy could not admit that he might be wrong, which is too bad because as the gentleman reminded me, I should drop my ego and face the facts. What I would appreciate from the rest of the truth movement is a little reciprocity.

Members Portal. The collapse of 7 World Trade Center was not a controlled demolition. Skeptoid Podcast 85 January 29, Podcast transcript Subscribe. Today we’re going to point our skeptical eye, once again, at the events of September 11, specifically at World Trade Center 7, the building that collapsed after the twin towers for no apparent reason, in a manner consistent with a controlled demolition. We’re entering the weird wild and wacky world of conspiracy theories, men in black, deceit, doubt, mistrust, and delusion.
But on which side? First let’s be clear about what the two sides are, then we’ll examine the evidence supporting each of them. The conspiracy theory states that World Trade Center 7 was a controlled demolition, an intentional destruction of the building by our government. The evidence supporting this theory is threefold: First, the video of the collapse and the tidy distribution of the resultant debris appear consistent with known controlled demolitions.
Second, photographs of the building before it collapsed showed little or no damage to cause a collapse. Third, fire alone cannot destroy a steel building, and so the cause must lie in high-energy explosives. A great deal more information is put forward by the supporters of this theory as evidence, but it’s really only suppositions about proposed motives and observations of events perceived as unusual, and so is actually not testable evidence of a direct physical cause.
This information includes government offices located in the building, the establishment of Giuliani’s emergency management headquarters on the 23 rd floor, and portions of the government’s preliminary reports that openly stated that certain unknowns remained.

The NIST claimed that embers ignited a fire which then caused the storey building to collapse on itself at p. For expediency and because it was not hit by a plane, the study looked only at WTC 7 not the other two but AET has long claimed all three were subject to something beyond heat induced failure. Further, he says, the debris from WTC 1 which fell feet to WTC 7 did not attain sufficient mass to cause structural damage to the steel in that building.
The bottom line, he says, is that the NIST report is flawed and of no value to future engineering or architectural learning. The Alaska report adds new momentum to long standing claims by the AET that all three of the buildings should not have collapsed in the spectacular and deadly manner they did. Further, and Korol underlines this, there was nothing in the offices beyond basic desks, chairs, computers and paper that would be of such a combustible nature so as to feed a fire and raise the temperature to above 1, degrees Celsius and melt the steel structure.
UAF civil engineering professor Leroy Hulsey, principal investigator, his research assistants, Feng Xiao, now an associate professor at Nanjing University of Science and Technology and Zhili Quan, now a bridge engineer for the South Carolina Department of Transportation, found that the design standard of the building was not exceeded by the fire and that simultaneous and controlled demolition caused the structural steel to fail.
It was also the first NIST finding of a highrise collapse from thermal deformation caused by fire which the page Alaska report disputes. It presents arguments showing it was a simultaneous global failure not a localized failure causing a domino effect. Hulsey et al argue that the collapse was straight down in a pancake fashion with about 2. The study team undertook extensive computer and physical modelling, paying particular attention to the area around Column 79 which had been identified as the critical juncture of failure.

Template:Pp-move-vandalism Template:Coord. The collapse of 2 World Trade Center seen from Williamsburg, Brooklyn. The twin towers of the World Trade Center collapsed on September 11, , as a result of the September 11 attacks ,  in which terrorists affiliated with al-Qaeda hijacked four commercial passenger jet airliners , flying one into the North Tower 1 World Trade Center and another into the South Tower 2 World Trade Center.
Later that day, 7 World Trade Center collapsed at p. Debris from the collapsing towers severely damaged or destroyed more than a dozen other adjacent and nearby structures. The Federal Emergency Management Agency FEMA completed its performance study of the buildings in May It declared that the WTC design had been sound, and attributed the collapses wholly to extraordinary factors beyond the control of the builders.
While calling for further study, FEMA suggested that the collapses were probably initiated by weakening of the floor joists by the fires that resulted from the aircraft impacts. According to FEMA’s report, the floors detached from the main structure of the building and fell onto each other, initiating a progressive „pancake“ collapse. FEMA’s early investigation was revised by a later, more detailed investigation conducted by the National Institute of Standards and Technology NIST , which also consulted outside engineering entities.
This investigation was completed in September Like FEMA, NIST vindicated the design of the WTC, noting that the severity of the attacks and the magnitude of the destruction was beyond anything experienced in U. NIST also emphasized the role of the fires, but it did not attribute the collapses to failing floor joists.
Instead, NIST found that sagging floors pulled inward on the perimeter columns: „This led to the inward bowing of the perimeter columns and failure of the south face of WTC 1 and the east face of WTC 2, initiating the collapse of each of the towers.
