Documents / FOIA release
This CIA release, approved for release on 2 April 2001, reproduces William Markowitz's 1967 Science article "The Physics and Metaphysics of Unidentified Flying Objects." Markowitz was a Marquette University physics professor. He argues that reported UFO landings and lift-offs cannot involve extraterrestrial spacecraft if the laws of physics hold. He criticizes the hard-data claims of Hynek, Powers and Vallee and recommends that the Air Force stop investigating UFOs.
