This previously-unpublished paper, Characterization of a World Trade Center Dust Sample, by F.R. Greening and T.N. Greening is listed here to encourage discussion and further research of the WTC dust or powder in the context of published results and analysis by other scientists and institutions.

Following September 11, 2001 (9/11), Congress in 2002 charged the National Institute of Standards and Technology (NIST) with determining how and why three steel-framed buildings in the World Trade Center (WTC) - the Twin Towers (WTC1/2) and Building 7 (WTC7) - collapsed. Never before or since 9/11 had steel-framed buildings been so completely destroyed purportedly by fire.

The NIST reports for the Twin Towers were published in 2005. In these reports, NIST violated the scientific method by failing to examine the actual fall of the Towers, as well as by ignoring other pertinent evidence from before and after the destructions. Observation and analysis of the way a building falls is usually the best indicator of the reason for its collapse or destruction. By the time NIST published its WTC1/2 reports, hundreds of highly-qualified scientists, engineers, architects and other scholars had concluded, after analyzing all available evidence, that the Towers (as well as WTC7) had been brought down by some form of controlled demolition.

Another major step in proper forensic investigations of completely-destroyed buildings is to analyze a building’s remains to determine whether explosives are present. National Fire Protection Association (NFPA) guidelines require this in cases of high-order damage. However, NIST itself never made such an examination. This examination was instead performed by others, such as the United States Environmental Protection Agency (EPA) [1], RJ Lee Company [2], the United States Geological Survey (USGS) [3] and independent scientists including Niels Harrit, Jeffrey Farrer, Steven E. Jones, and Kevin Ryan [4] who examined the WTC dust or powder. All of these studies found a high percentage of iron microspheres which require high temperatures for their formation. Harrit, Farrer et al.[4] also found red/gray chips where the red layer exhibited the properties of super-thermite incorporating nanotechnology, a material with explosive and incendiary properties.

Comments on the paper by F.R. Greening and T.N. Greening are invited.

I am the person who provided the 9/11 dust samples to Professor Frank Greening who has recently submitted a dust analysis to you. If anyone requires verification from me please refer to my email and ask them to write 9/11 in the title.

If you have any questions please do not hesitate to contact me. Thank you.

"Dear Ms Sakoutis,
Thank you very much for contacting us and confirming the origin of the WTC dust sample that is the subject of the paper by F.R. Greening and T.N. Greening. Thank you for your thoughtfulness in preserving some of the dust you acquired that day. As you may know, our website engages in scientific discussion of submitted papers with the purpose of determining what took place on 9/11. We are in contact with other independent scientists who may be interested in examining WTC dust samples. Would you be able and willing to provide samples, similar to the one you gave Dr. Greening, for examination by other scientists? Thanks again for contacting us, this is an important part of the ongoing 9/11 research."]
