Yep now we know!
NIST took 7 years and made it all up, a fake report!
Using NIST's claim that column 79 buckled causing a progressive collapse, something truthers were smart enough to figure out was bs right from the begining, now we have the fea to prove it!
NIST claim, Failure of Columns 76 to 81, this is how the building would have fell if that were true!
4.7 Summary and Conclusion
In summary, several findings were made from the analyses above:
1.Columns 79, 80, and 81 did not fail at the lower floors of the building. Instead, they needed to have failed at the upper floors of the building all the way to the penthouse. Yet there were no documented fires above Floor 30.
Therefore, fire did not cause the collapse of Columns 79, 80, and 81nor the collapse of the east penthouse.
2.The hypothetical failure of Columns 79, 80, and 81 —the three eastern most core columns —would not trigger a horizontal progression of core column failures. 110
Therefore, the hypotheses of NIST, Arup/Nordenson, and Weidlinger that the buckling of Column 79 would trigger a progressive collapse of the entire building are invalid, and the collapse of Columns 79, 80, and 81 high in the building was a separate and distinct event.
3.Even if we assume the failure of Columns 79, 80, and 81 could lead to the failure of the next row of core columns, the hypothetical failure of Columns 76 to 81 would overload the exterior columns around the southeast corner of the building, rather than overloading the next row of core columns to the west, which would result in the building tipping to the southeast and notina straight-down collapse.
4.The simultaneous failure of all core columns over 8 stories followed 1.3seconds later by the simultaneous failure of all exterior columns over 8 stories produces almost exactly the behavior observed in videos of the collapse.
The collapse could have started at various floors starting at Floor 16 and below and produced the same behavior.It is our conclusion that the collapse of WTC 7 was a global failure involving the near-simultaneous failure of all columns in the building and not a progressive collapse involving the sequential failure of columns throughout the building.Despite simulating a number of hypothetical scenarios, we were unable to identify any progressive sequence of failures that could have taken place on September 11, 2001, and caused a total collapse of the building, let alone the observed straight-down collapse with approximately 2.5 seconds of free fall and minimal differential movement of the exterior.
Last week, AE911Truth, along with researchers at the University of Alaska Fairbanks, released the draft report of a four-year computer modeling study of the tower’s collapse. “The report confirms what most Americans suspect when they see the collapse,” said Walter. “Building 7 did not come down from fires.”
WHAT DID NIST SAY:
Diagram 1-Typical WTC 7 floor showing locations of columns (numbered). The buckling of Column 79 was the initiating event that led to the collapse of WTC 7. The buckling resulted from fire-induced damage to floors around column 79, failure of the girder between Columns 79 and 44, and cascading floor failures.
1.75 to 4.0 seconds): gravitational acceleration (free fall)
Thermite is a combination of aluminum powder and a metal oxide that releases a tremendous amount of heat when ignited. It is typically used to weld railroad rails together by melting a small quantity of steel and pouring the melted steel into a form between the two rails.
To apply thermite to a large steel column, approximately 0.13 lb of thermite would be needed to heat and melt each pound of steel. For a steel column that weighs approximately 1,000 lbs. per foot, at least 100 lbs. of thermite would need to be placed around the column, ignited, and remain in contact with the vertical steel surface as the thermite reaction took place. This is for one column . presumably, more than one column would have been prepared with thermite, if this approach were to be used.
After viewing video footage of the controversial building collapse from four different angles, 52% of Americans who participated in the survey are either sure or suspect it was caused by a controlled demolition
