Scientists Find Unignited Explosive Residues in WTC Dust
Red/Gray Chips Match Advanced Thermitic Materials Developed in US Government Labs
by Gregg Roberts
The team analyzed dust samples that were collected from four locations near Ground Zero. One sample was collected ten minutes after the North Tower exploded, so it could not have been contaminated with particles from the cleanup efforts. All four samples contained the same unusual, tiny red/gray chips, which turned out to consist not only of the ingredients of conventional thermite but also carbon, silicon, and other elements.
