A sceptic. Across decades of famous cases, Philip J. Klass offered the conventional answer. In his 1974 book UFOs Explained, he called the Pascagoula abduction a hoax. In June 1976 he made public a failed polygraph from the Travis Walton case, one the National Enquirer had paid for, and pointed to a possible motive. For the 1976 Tehran incident, he argued the main light was Jupiter. On June 24, 1987, he debated Stanton T. Friedman on ABC Nightline over the MJ-12 documents. His claim was that Truman's signature there was a pasted photocopy.
