Great Post Patrick!!
You explain things very eloquently.

dotcoma, I am an American. I use farenheit I dont know the formula for F = C.

Quote by: dotcoma, Oh, and how many times do you need to hear from people who do have experience with the towers that there was no melting, but rather the beams were just made unstable by the heat?

First of all there was molten metal in the basements of both main towers and WTC7 (more on that below). Also, I already addressed that with this letter from a structural engineer for UL:

We know that the steel components were certified to ASTM E119. The time temperature curves for this standard require the samples to be exposed to temperatures around 2000F for several hours. And as we all agree, the steel applied met those specifications. Additionally, I think we can all agree that even un-fireproofed steel will not melt until reaching red-hot temperatures of nearly 3000F (2). Why Dr. Brown would imply that 2000F would melt the high-grade steel used in those buildings makes no sense at all. <snip> However the summary of the new NIST report seems to ignore your findings, as it suggests that these low temperatures caused exposed bits of the building's steel core to "soften and buckle"(5). Additionally this summary states that the perimeter columns softened, yet your findings make clear that "most perimeter panels (157 of 160) saw no temperature above 250C". To soften steel for the purposes of forging, normally temperatures need to be above 1100C (6). However, this new summary report suggests that much lower temperatures were be able to not only soften the steel in a matter of minutes, but lead to rapid structural collapse. <snip> This story just does not add up. If steel from those buildings did soften or melt, I'm sure we can all agree that this was certainly not due to jet fuel fires of any kind, let alone the briefly burning fires in those towers. That fact should be of great concern to all Americans. Alternatively, the contention that this steel did fail at temperatures around 250C suggests that the majority of deaths on 9/11 were due to a safety-related failure. That suggestion should be of great concern to my company.

Which brings us back to exactly why we need to have open public hearings for the WTC structural failure. The topic of this thread. If all towers are death traps for fire fighters who rush in to save lives only to be crushed because the building code is lax. This is immoral. Evil. On the other hand. If thermite explosives were used at the core where the structure is attatched to bedrock. Which would explain molten metal 3 months later even though there was no oxygen to fuel this molten mess smothered in debris

How do you explain the molten steel found at bedrock?

Exclusive to American Free Press By Christopher Bollyn American Free Press has learned of pools of “molten steel” found at the base of the collapsed twin towers weeks after the collapse. Although the energy source for these incredibly hot areas has yet to be explained, New York seismometers recorded huge bursts of energy, which caused unexplained seismic “spikes” at the beginning of each collapse. These spikes suggest that massive underground explosions may have literally knocked the towers off their foundations, causing them to collapse. In the basements of the collapsed towers, where the 47 central support columns connected with the bedrock, hot spots of “literally molten steel” were discovered more than a month after the collapse. Such persistent and intense residual heat, 70 feet below the surface, in an oxygen starved environment, could explain how these crucial structural supports failed. Peter Tully, president of Tully Construction of Flushing, N.Y., told AFP that he saw pools of “literally molten steel” at the World Trade Center. Tully was contracted after the Sept. 11 tragedy to re move the debris from the site. <snip> AFP asked Loizeaux about the report of molten steel on the site. “Yes,” he said, “hot spots of molten steel in the basements.” These incredibly hot areas were found “at the bottoms of the elevator shafts of the main towers, down seven [basement] levels,” Loizeaux said. The molten steel was found “three, four, and five weeks later, when the rubble was being removed,” Loizeaux said. He said molten steel was also found at 7 WTC, which collapsed mysteriously in the late afternoon. Construction steel has an extremely high melting point of about 2,800 degrees Fahrenheit. Asked what could have caused such extreme heat, Tully said, “Think of the jet fuel.” Loizeaux told AFP that the steel-melting fires were fueled by “paper, carpet and other combustibles packed down the elevator shafts by the tower floors as they ‘pancaked’ into the basement.” However, some independent investigators dispute this claim, saying kerosene-based jet fuel, paper, or the other combustibles normally found in the towers, cannot generate the heat required to melt steel, especially in an oxygen-poor environment like a deep basement.

How do you explain away these seismic spikes?

Link The above image is a seismographical readout at the time of the attacks and collapse of the WTC. You can clearly see on the top line the small peaks of the planes impacts. But here is where it gets interesting, check out those two really BIG spikes on the 3rd and 4th lines. Those spikes represent the collapse of the towers. Notice the shape of these spikes, the highest peak is actually at the beginning. A strange anomaly when you consider the nature of a collapse is more gradual than explosive, with the vibrations becoming more and more intense as each floor collapses onto the next. But this isnt the case in the seismograph. The Palisades seismic data recorded a 2.1 magnitude earthquake during the 10-second collapse of the South Tower at 9:59:04 and a 2.3 quake during the 8-second collapse of the North Tower at 10:28:31.
