Continuing my series of posts (see Example 1and Example 2 )on why laypersons should want a further investigation of 9/11, I come to the yellow molten metal pouring from the South Tower, shortly before its collapse. Watch for example, this video:
Though NIST did not initially investigate the nature of phenomenon, in a reply to frequently asked questions (republished with comments by Jim Hoffman), they do offer an answer to a question about it:
11. Why do some photographs show a yellow stream of molten metal pouring down the side of WTC2 that NIST claims was aluminum from the crashed plane although aluminum burns with a white glow?
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.
But as Mr. Hoffman noted, physics professor Steven E. Jones had tried unsuccessfully to reproduce the yellow appearance by mixing molten aluminum with "hot, partially burned, solid organic materials."
So what NIST would need to do is experimentally verify their hypothesis that the yellow molten metal could indeed have been aluminum. As far as I know, neither NIST (nor anyone else) has bothered to do so.
But one might inquire why this is relevant evidence that NIST needs to investigate. I would suggest that NIST made it relevant by bothering to offer an answer to what the molten material might be. Had NIST ignored the question or said that determining its nature wasn't relevant, then we laypeople might not have reason to demand that they investigate the matter further. But since NIST went to the trouble of trying to answer the question, they themselves made it relevant to the investigation.
But why might this be relevant to an investigation of the collapse of the South tower?
Thermite vs Safe is my favorite example of showing what thermite can do and what it looks like while doing it:
So is this what the yellow molten metal was that was pouring from the South Tower on 9/11? If not, then what was it?
