In the past half century of UFOlogy, one man stands out, among a sea of believers, as the definitive skeptic of all matters flying saucers and aliens. This interview with Philip J. Klass (1919–2005), one of the last he gave of his career, goes inside his investigations into the claims of extraterrestrial investigations. This interview was published in Skeptic magazine volume 7, number 4 in 1999.
