[Source: RJ Lee Group]A laboratory releases two reports focusing on the unique properties of the dust from the World Trade Center collapses, and finds evidence of extremely high temperatures involved in these collapses. The laboratory, RJ Lee Group of Pennsylvania, is the largest commercial electron microscope laboratory in the world. [RJ LeeGroup, Inc., 5/2004, pp. 1 pdf file] In April 2002, it was retained on behalf of Deutsche Bank Trust Company Americas to investigate environmental contaminants in this company’s building at 130 Liberty Street, New York. [RJ LeeGroup, Inc., 12/2003, pp. 1 pdf file] The building, located next to the World Trade Center, was heavily damaged on September 11, suffering a 24-story gash when the South Tower collapsed. [New York Times, 6/20/2003; Real Estate Weekly, 9/14/2005] RJ Lee collected samples from it, which it then analyzed “using industry standard analytical laboratory methods.” [RJ LeeGroup, Inc., 12/2003, pp. 3-4 pdf file] In December 2003 and May 2004, it releases two reports that evaluate the features of the dust from the WTC that was deposited in 130 Liberty Street. It calls this evaluation “the most extensive microscopic investigation related to WTC dust ever performed.” [RJ LeeGroup, Inc., 12/2003, pp. 1-2 pdf file; RJ LeeGroup, Inc., 5/2004, pp. 4 pdf file] The reports describe phenomena that indicate extremely high temperatures were involved in the WTC collapses:
bullet “Various metals (most notably iron and lead) were melted during the WTC event, producing spherical metallic particles. Exposure of phases to high heat results in the formation of spherical particles due to surface tension.” [RJ LeeGroup, Inc., 12/2003, pp. 17 pdf file]
bullet “The amount of energy introduced during the generation of the WTC dust and the ensuing conflagration caused various components to vaporize.… Many of the materials, such as lead, cadmium, mercury, and various organic compounds, vaporized and then condensed during the WTC event.” [RJ LeeGroup, Inc., 12/2003, pp. 21 pdf file]
bullet “An additional characteristic of WTC dust is the presence of coated particles and fibers.… The presence of lead oxide on the surface of mineral wool indicate the existence of extremely high temperatures during the collapse which caused metallic lead to volatilize, oxidize, and finally condense on the surface of the mineral wool.” [RJ LeeGroup, Inc., 5/2004, pp. 12 pdf file]
bullet “WTC dust markers exhibit characteristics of particles that have undergone high stress and high temperature. Asbestos in the WTC dust was reduced to thin bundles and fibrils as opposed to the complex particles found in a building having asbestos-containing surfacing materials. Gypsum in the WTC dust is finely pulverized to a degree not seen in other building debris. Mineral wool fibers have a short and fractured nature that can be attributed to the catastrophic collapse. Lead was present as ultra fine spherical particles. Some particles show evidence of being exposed to a conflagration such as spherical metals and silicates, and vesicular particles (round open porous structure having a Swiss cheese appearance as a result of boiling and evaporation).” [RJ LeeGroup, Inc., 5/2004, pp. 17-18 pdf file]
The reports offer no explanation for the origins of the extremely high temperatures that are indicated. But physics professor Steven E. Jones (see November 8, 2005) will later claim that molten metal found in the debris of the WTC is evidence that the towers were brought down deliberately and involving the use of an incendiary substance called thermite, which can melt steel.
