The FBI has put many of its old files on the Web for anyone to see. There's fascinating stuff there, about 1960s anti-war radicals, and old-time movie stars, and the hunt for the outlaws Bonnie and Clyde . But the file that has interested people most is one from 1950 titled FLYING SAUCERS. It is a memo about a report from an Air Force investigator that three flying saucers had been recovered in New Mexico. The report said three bodies were found in each of the three saucers. They were human-like and dressed in a fine metallic material, and they were only three feet tall. There is no indication that the recipient took the third-hand report seriously. It was one of a rash of similar incidents around that time. A million people have read it recently on the Web, though.
