Tiny red and gray chips found in the dust from the collapse of the World Trade Center contain highly explosive materials - proof, according to a former BYU professor, that 9/11 is still a sinister mystery. Physicist Steven E. Jones, who retired from Brigham Young University in 2006 after the school recoiled from the controversy surrounding his 9/11 theories, is one of nine authors on a paper published last week in the online, peer-reviewed Open Chemical Physics Journal. Also listed as authors are BYU physics professor Jeffrey Farrer and a professor of nanochemistry at the University of Copenhagen in Denmark. For several years, Jones has theorized that pre-positioned explosives, not fires from jet fuel, caused the rapid, symmetrical collapse of the two World Trade Center buildings, plus the collapse of a third building, WTC-7. The newest research, according to the journal authors, shows that dust from the collapsing towers contained a nano-thermite" material that is highly explosive. A layer of dust lay over parts of Manhattan immediately following the collapse of the towers, and it was samples of this dust that Jones and fellow researchers requested in a 2006 paper, hoping to determine "the whole truth of the events of that day." They eventually tested four samples they received from New Yorkers. Red/gray chips ... were found in all four dust samples. The chips were then analyzed using scanning electron microscopy and other high-tech tools. The red layer of the chips, according to the researchers, contains a "highly energetic" form of thermite.
