Edward Ruppelt was the first head of the U.S. Air Force's Project Blue Book, the official project initiated to investigate UFO reports beginning in 1952. This report from 1956 takes us inside these initial investigations, separates fact from fiction, and gives insight into who, when, where, and how sightings were reported and researched in open-minded fashion (for which Ruppelt was renowned), rather than in the typical hushed and secretive (and censored) manner most often associated with government and military reports which are released to the public.
