Source S-1 got his name because the return address and many of the documents had a -1 on the first page. The return address is Las Vegas, Nevada, and he mailed information on three different occasions during the summer with postmarks of Big Bear Lake and Fort Meade, Maryland with return addresses of Las Vegas and a suspiciously torn (not there) return address. The materials supplied included some typed personal cover letters to Tim Cooper of which one, the IMPORTANT memo, is posted on this site. Other photographs arrived as undeveloped film and upon developing were pictures taken of a TV displaying the Santilli film.
