Fred Lee Crisman (July 22, 1919 - December 10, 1975) was a fighter pilot and later educator from Tacoma, Washington known for claims of paranormal events and ties to 20th century conspiracies. In 1946, Crisman claimed to have battled with non-humans in caves during the second World War. The following year, he attempted to convince two early flying saucer witnesses that lava rocks were in fact debris dropped from a flying saucer. In 1968, Crisman was subpoenaed by a New Orleans grand jury in the prosecution of local man for the assassination of President John F. Kennedy -- a prosecution that would later be dramatized in 1991 Oliver Stone film JFK.
