Electron microscopy reveals similarities to WTC thermite residue. Dr. Steven Jones just turned in these electron microscope images of thermite residue from the September 2, 2007 TruthBurn demonstration at Burning Man. Iron rich spheres that look very similar to WTC iron spheres were revealed by the powerful microscope at Jones' lab. An analysis is forthcoming.
