Read more about Modern History, 7th tower 9/11. Building 7 was a storey skyscraper that formed part of the World Trade Center complex. Fires broke out on multiple floors of the structure, and at devildice on that world-changing day — many hours after the Twin Towers fell — Building 7 collapsed.

It did not collapse from explosives or from diesel fuel fires. Conspiracy theorists have long pointed to the collapse of the story structure as key evidence that the U. No planes struck the building, and the commonly available views of the exterior didn't show significant damage. Since WTC 7 housed Secret Service and CIA offices, conspiracy theorists claimed that the building was destroyed in a controlled demolition in order to obliterate evidence of the U. It is physically impossible," she said. Today's report confirms that a fire was, indeed, the cause. The final report describes how debris from the collapse of WTC 1 ignited fires on at least 10 floors of WTC 7 at the western half of the south face. Fires on Floors 7 through 9 and 11 through 13 burned out of control, because the water supply to the automatic sprinkler system had failed. The primary and backup water supply to the sprinkler systems for the lower floors relied on the city's water supply. Those water lines were damaged by the collapse of WTC 1 and 2. These uncontrolled fires in WTC 7 eventually spread to the northeast part of the building, where the collapse began. After 7 hours of uncontrolled fires, a steel girder on Floor 13 lost its connection to one of the 81 columns supporting the building. Floor 13 collapsed, beginning a cascade of floor failures to Floor 5. Column 79, no longer supported by a girder, buckled, triggering a rapid succession of structural failures that moved from east to west.

Explicit adoption of the "structural frame" approach to fire resistance ratings that requires all members of the primary structural frame to have the higher fire resistance rating commonly required for columns. If you value your job, you better go along with what the government says. 7th tower 9/11 control databases.

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.

The team found that the design of WTC 7 in the s was generally consistent with the New York City building code in effect at that time. WTC 7's designers intended its stairwells to evacuate nearly 14, occupants, anticipated at the time to be the maximum occupancy of the building.

Two commercial airliners hijacked by al-Qaeda terrorists were deliberately flown into the Twin Towers of the complex, resulting in a total progressive collapse that killed almost 3, people. It is the deadliest and most costly building collapse in history. The towers' destruction caused major devastation throughout Lower Manhattan , and more than a dozen adjacent and nearby structures were damaged or destroyed by debris from the plane impacts or the collapses. Four of the five remaining World Trade Center structures were immediately crushed or damaged beyond repair as the towers fell, while 7 World Trade Center remained standing for another six hours until fires ignited by raining debris from the North Tower brought it down at that afternoon.

Scott Grainger May 20, Building 7 was a full metres away from the nearest of the Twin Towers the North Tower , and was separated from it by another major building WTC 6. Manhattan , New York City. World Trade Center. It is unlikely that lbs. WTC 7's collapse, viewed from the exterior most videos were taken from the north , did appear to fall almost uniformly as a single unit. Thermate also contains sulfur and sometimes barium nitrate, both of which increase the compound's thermal effect, create flame in burning, and significantly reduce the ignition temperature. 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. On a similar note, US counter-terrorism official Richard Clarke refuted the significance of the CIA occupying Building 7, emphasising that this was simply a commercial office building in downtown New York, and there was nothing particularly unusual about government agencies leasing office space there like anybody else. The symmetric appearance of the downward fall of WTC 7 was primarily due to the greater stiffness and strength of its exterior frame relative to the interior framing. Just looking at the video clips of the story building dropping symmetrically, with little deformation reveals to most open-people that it was a controlled demolition. The building had only half the number of occupants on a typical day-with approximately 4, occupants-at the times the airplanes struck the towers. The fate of the fuel of two 6, gallon tanks was also unknown. Archived from the original on December 11, The building was 10 percent leased by August

This is awesome news but the Sheople are still in passive mode, waiting to be told what to think or how to respond to a yet complicit mainstream media determined to keep them in the dark and under established, corporate control. What followed in rapid succession was a series of structural failures. September August 8, Why did NIST withhold from public release limited and specific input and results files for certain collapse models used in the WTC 7 study? I hope this will indeed aid in disseminating the truth about Building 7 and the other buildings of the World Trade Center complex on that fateful day in September Daily News New York. Created September 13, , Updated April 5, Were there any discrepancies between the results of the partial floor model and the story model? Archived from the original on March 25, Published in , its report confirmed that fires raged in an uncontrolled fashion after the building was hit by North Tower debris.
