Architects and Engineers for 9/11 Truth

The World Trade Center dust is remarkable due not only to its having blanketed Lower Manhattan 4” to 12” thick in many places, but also for the dark secrets that it would reveal.

Iron-rich microspheres were so common in the WTC dust that EPA’s WTC panel discussed their use as one of the signature components to distinguish the WTC dust from so-called “background” dust (i.e. common office-building dust).

RJ Lee Group, evaluating the contamination of the Deutsche Bank building at 130 Liberty Street, also described these iron-rich spheres, and actually used them as one of their signature markers. In other words, dust wasn’t regarded as WTC dust unless it contained these spheres. The chemical composition and micro-images of two WTC iron-rich spheres were documented by the US Geological Survey.

The fraction of microspheres in the dust varied (between 0.2 and 1.3 % for USGS outdoor samples and a mean of 5.87% for all RJ Lee samples) depending on the area where the samples were taken. Due to their shape and density, the spheres were not likely to have traveled as far as other components of the dust. The diameter of the spheres in two evaluated dust samples ranged from about one micron (0.001 mm) to 1.5 mm.

The microspheres must have been formed at extremely high temperatures during the World Trade Center’s destruction – temperatures exceeding the melting point of iron (~2,700° F). The spheres must have been molten when they were created in order to take their spherical shape. Such high temperatures could not have been produced by jet fuel or office building fires, which reach only up to 1,800 °F under the most severe fire conditions. However, the thermite reaction produces molten iron and aluminum oxide as the reaction products. After being ejected into the atmosphere, molten iron droplets would be pulled into roughly spherical shapes by surface tension. They would then cool, solidify, and fall out – preserving in their spherical shape the information that they were once molten, and preserving in their chemical signature information about their origin.
