Engineers call the process "pancaking," and it does not require an explosion to begin, according to David Biggs, a structural engineer at Ryan-Biggs Associates and a member of the American Society of Civil Engineers (ASCE) team that worked on the FEMA report. Fine Underwriters Laboratories did the testing for the NIST after 9/11; there needs to be solid evidence they did it prior to 9/11; and that ASTM E119 was applicable to real world conditions after commercial jetliners crashed into the towers; and their sprayed on fireproofing withstood planes crashes at full speed. With columns on the south face apparently damaged, high stresses would likely have been communicated to columns on the building's other faces, thereby exceeding their load-bearing capacities. Damaged by falling debris, the building then endures a fire that rages for hours. Scientists disprove the claim with the more detailed graph 2 (below). “I only said that that’s what it looked like.”, Romero, who agrees with the scientific conclusion that fire triggered the collapses, demanded a retraction from the Journal. It was printed Sept. 22, 2001.

Unable to absorb the massive energy, that floor would fail, transmitting the forces to the floor below, allowing the collapse to progress downward through the building in a chain reaction. The impact and ensuing fires disrupted elevator service in both buildings. NIST also believes that a great deal of the spray-on fireproofing insulation was likely knocked off the steel beams that were in the path of the crashing jets, leaving the metal more vulnerable to the heat. But subsequent studies have shown that the WTC’s structural integrity was destroyed by intense fire as well as the severe damage inflicted by the planes. As Debunking 9/11 Myths explains, jet fuel burns between 1,100 and 1,200 degrees Celsius, well below the 1,510 degrees necessary to melt steel.

WhatReallyHappened.com chooses to display only one graph (Graph 1), which shows the readings over a 30-minute time span. However, experts agree that for the towers to collapse, their steel frames didn’t need to melt, they just had to lose some of their structural strength—and that required exposure to much less heat. “The doors cracked open on the lobby floor and flames came out and people died,” says James Quintiere, an engineering professor at the University of Maryland and a NIST adviser. It is noted that none of the college professors or academics who have espoused these theories have any expertise in engineering, … Or the need to solve a Case. Debunking 9/11 myths.

Debunking 9/11 Myths expands that investigation to include the 20 most prominent and persistent claims underlying the conspiracy theories, focusing on concrete, physical facts rather than political hypothesizing. But NIST's analysis suggests the fall of WTC 7 was an example of "progressive collapse," a process in which the failure of parts of a structure ultimately creates strains that cause the entire building to come down. Investigators believe the fire was fed by tanks of diesel fuel that many tenants used to run emergency generators. "The jet fuel was the ignition source," Williams tells PM. “What our preliminary analysis has shown is that if you take out just one column on one of the lower floors,” Sunder notes, “it could cause a vertical progression of collapse so that the entire section comes down.”. Investigators believe the fire was fed by tanks of diesel fuel that many tenants used to run emergency generators. Was the Pentagon really struck by a missile?
