deseretnews.com | Physicist says heat substance felled WTC: "EPHRAIM — A Brigham Young University physicist said he now believes an incendiary substance called thermite, bolstered by sulfur, was used to generate exceptionally hot fires at the World Trade Center on 9/11, causing the structural steel to fail and the buildings to collapse.
'It looks like thermite with sulfur added, which really is a very clever idea,' Steven Jones, professor of physics at BYU, told a meeting of the Utah Academy of Science, Arts and Letters at Snow College Friday.
The government requires standard explosives to contain tag elements enabling them to be traced back to their manufacturers. But no tags are required in aluminum and iron oxide, the materials used to make thermite, he said. Nor, he said, are tags required in sulfur.
Jones is co-chairman, with James H. Fetzer, a distinguished professor of philosophy at the University of Minnesota of Scholars for 9/11 Truth, a group of college faculty members who believe conspirators other than pilots of the planes were directly involved in bringing down New York's Trade Towers."
