    even if this was not my profession, it would be stupid, but because it is my profession it is just an insult. there have been hundreds of engineers of many subdisciplines calling out these stupidities from the get go. and people forget that there has not been a complete official explanation for this.

          Thanks, I'll watch them when I have time.

          I'll also take a look at this study I found after a quick search

          https://web.archive.org/web/20150907011050/http://www.911research.wtc7.net/mirrors/bentham_open/ActiveThermitic_Harrit_Bentham2009.pdf

          To be honest, because the controlled demolition theory seems so implausible to me, just the whole operation that would be involved, I'm gonna need some strong arguments that a high-energy event like the WTC collisions, fires, and collapses could not create, e.g., CNTs, or microspheres. It's not my area but I do have a little relevant background and it doesn't seem implausible to me.

          There's also this article I found in my admittedly brief search on the topic:

          https://www.machinedesign.com/home/article/21830429/another-blow-for-wtc-conspiracy-theorists

          They claim that red-gray chips and iron-rich microspheres found in WTC dust are residue from thermite fires that support their idea about thermite.

          But this claim took a hit this spring when the microscopy consulting firm MVA Scientific Consultants in Duluth, Ga. released a study of these chips collected from WTC dust. They used a stereomicroscope and polarized light microscopy, among other things, to analyze the samples. MVA says the analytical procedures used to characterize the red/gray chips were based on recommended guidelines for forensic identification of explosives and the ASTM standard guide for forensic paint analysis and comparison. Scientists there ran additional tests an the samples that included Fourier transform infrared spectroscopy (FTIR); SEM-EDS of cross-sections; low temperature ashing and residue analysis by transmission electron microscopy (TEM) with selected area electron diffraction (SAED) and EDS; and several other more involved methods.

          Their conclusion: There is no evidence of individual elemental aluminum particles that you would expect to see from a thermite burn. They say the red/gray chips found in the WTC dust at four sites in New York City are consistent with a carbon-steel coated with an epoxy resin that contains primarily iron oxide and kaolin clay pigments. And there is no evidence of individual elemental aluminum particles of any size in the red/gray chips, so the red layer of the red/gray chips is not thermite or nano-thermite.

          And WTC conspiracy theorists' claim that microscopic spheres of iron found in WTC dust could only have been formed with thermite was recently debunked by a group called New Mexicans for Science and Reason who pointed out that very small metal particles have a much lower melting point than bulk material. Wires and filaments from electronics in the WTC are the likely source of the microspheres. The NMSR group even produced a YouTube video showing how to create your own microspheres by burning steel wool: http://www.youtube.com/watch?v=jZ9wSD4Hcys&list=UUb1Lcha1B51ChVrbBi548OA&index=2&feature=plcp

          I'll be sure to watch the videos when I have time and learn more about the topic, thanks for sending them to me

            not to be confused, i am not saying that it was definitely a controlled demolition, it may ver well be something else. but it is far more closer to a demolition than anything put forward by nist.
