At a May 1, 2009 presentation at UC Davis, California, physics professor, Steven Jones discusses the new paper, Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe by Niels H. Harrit, Jeffrey Farrer, Steven E. Jones, Kevin R. Ryan, Frank M. Legge, Daniel Farnsworth, Gregg Roberts, James R. Gourley and Bradley R. Larsen.
Steven explores some of the startling facts revealed in the paper and discusses some of the threats he's received over publishing his historic work.
The paper ends with this sentence: Based on these observations, we conclude that the red layer of the red/gray chips we have discovered in the WTC dust is active, unreacted thermitic material, incorporating nanotechnology, and is a highly energetic pyrotechnic or explosive material.
In short, the paper explodes the official story that no evidence exists for explosive/pyrotechnic materials in the WTC buildings.
What is high-tech explosive/pyrotechnic material in large quantities doing in the WTC dust? Who made tons of this stuff and why? Why have government investigators refused to look for explosive residues in the WTC aftermath?
These are central questions raised by this scientific study.
The peer-review on this paper was grueling, with pages of comments by referees. The tough questions the reviewers raised led to months of further experiments. These studies added much to the paper, including observation and photographs of iron-aluminum rich spheres produced as the material is ignited in a Differential Scanning Calorimeter (see Figures 20, 25 and 26).
The nine authors undertook an in-depth study of unusual red-gray chips found in the dust generated during the destruction of the World Trade Center on 9/11/2001. The article states: The iron oxide and aluminum are intimately mixed in the red material. When ignited in a DSC device the chips exhibit large but narrow exotherms occurring at approximately 430 C, far below the normal ignition temperature for conventional thermite. Numerous iron-rich spheres are clearly observed in the residue following the ignition of these peculiar red/gray chips. The red portion of these chips is found to be an unreacted thermitic material and highly energetic. The images and data plots deserve careful attention.
