Hey Walt, still no dvd from you. Harrit here is a very credible scientist. I have looked at his group's papers, seem solid technically. This is peer reviewed work. Note that he does not believe thermite was used to bring the towers down. The US geological survey and the independent lab that investigated the Deutsche Bank Dust for the Bank, they found "strange stuff" as well. The USGS for God's sake. Following Harrit I think is worthwhile.
