911 why debunkers cant face the facts

Con contends that debunkers refuse to address some specific issues during debates about the possibility of controlled demolition before the collapse of the World Trade Center on Sept. 11, 2001. Melted Steel From NIST's Investigation Report in 2006: "NIST reported (NCSTAR 1-5A) that just before 9:52 a.m., a bright spot appeared at the top of a window on the 80th floor of WTC 2, four windows removed from the east edge on the north face, followed by the flow of a glowing liquid. This flow lasted approximately four seconds before subsiding. Many such liquid flows were observed from near this location in the seven minutes leading up to the collapse of this tower. There is no evidence of similar molten liquid pouring out from another location in WTC 2 or from anywhere within WTC 1. Photographs, and NIST simulations of the aircraft impact, show large piles of debris in the 80th and 81st floors of WTC 2 near the site where the glowing liquid eventually appeared. Much of this debris came from the aircraft itself and from the office furnishings that the aircraft pushed forward as it tunneled to this far end of the building. Large fires developed on these piles shortly after the aircraft impact and continued to burn in the area until the tower collapsed. NIST concluded that the source of the molten material was aluminum alloys from the aircraft, since these are known to melt between 475 degrees Celsius and 640 degrees Celsius (depending on the particular alloy), well below the expected temperatures (about 1,000 degrees Celsius) in the vicinity of the fires. Aluminum is not expected to ignite at normal fire temperatures and there is no visual indication that the material flowing from the tower was burning. Pure liquid aluminum would be expected to appear silvery. However, the molten metal was very likely mixed with large amounts of hot, partially burned, solid organic materials (e.g., furniture, carpets, partitions and computers) which can display an orange glow, much like logs burning in a fireplace. The apparent color also would have been affected by slag formation on the surface. NIST investigators and experts from the American Society of Civil Engineers (ASCE) and the Structural Engineers Association of New York (SEONY)"who inspected the WTC steel at the WTC site and the salvage yards"found no evidence that would support the melting of steel in a jet-fuel ignited fire in the towers prior to collapse. The condition of the steel in the wreckage of the WTC towers (i.e., whether it was in a molten state or not) was irrelevant to the investigation of the collapse since it does not provide any conclusive information on the condition of the steel when the WTC towers were standing. NIST considered the damage to the steel structure and its fireproofing caused by the aircraft impact and the subsequent fires when the buildings were still standing since that damage was responsible for initiating the collapse of the WTC towers. Under certain circumstances it is conceivable for some of the steel in the wreckage to have melted after the buildings collapsed. Any molten steel in the wreckage was more likely due to the high temperature resulting from long exposure to combustion within the pile than to short exposure to fires or explosions while the buildings were standing." [1] However unconvincing Pro may find it, there can be little argument that the NIST directly addressed concerns about molten steel here. Evidence of Thermite The only WTC Debris which exhibits evidence of thermite was proffered by Dr. Steven Jones. NIST rejected Jones' findings citing the lack of a clear "chain of control." That is, the sample had not been protected from potential contamination in a scientifically rigorous way. No examination of WTC material that did meet scientifically rigorous controls has ever demonstrated evidence of thermite. Hundreds of demolitions experts evaluated the debris pile in the weeks after the 9/11 and none found evidence consistent thermite, nano-thermite or other explosives. NIST responds: a very large quantity of thermite (a mixture of powdered or granular aluminum metal and powdered iron oxide that burns at extremely high temperatures when ignited) or another incendiary compound would have had to be placed on at least the number of columns damaged by the aircraft impact and weakened by the subsequent fires to bring down a tower. Thermite burns slowly relative to explosive materials and can require several minutes in contact with a massive steel section to heat it to a temperature that would result in substantial weakening. Separate from the WTC towers investigation, NIST researchers estimated that at least 0.13 pounds of thermite would be required to heat each pound of a steel section to approximately 700 degrees Celsius (the temperature at which steel weakens substantially). Therefore, while a thermite reaction can cut through large steel columns, many thousands of pounds of thermite would need to have been placed inconspicuously ahead of time, remotely ignited, and somehow held in direct contact with the surface of hundreds of massive structural components to weaken the building. This makes it an unlikely substance for achieving a controlled demolition.[1] The Engergetic Materials Research and Testing Center was unable to cut a vertical steel column using thermite, even when the columns were significantly smaller than WTC columns.[2] Again, Pro need not be convinced by these finding. Con is not debating the relative value of pro-demoltion expert findings vs. debunkers. At issue in this debate is whether debunkers like the NIST are willing to address questions about molten steel and thermite. Pro has put forward that debunkers "never face" these arguments. As demonstrated here and with great repetition across the internet, debunkers do address these arguments with regularity. [1] http://www.webcitation.org... [2] http://channel.nationalgeographic.com...
