The Harry Truman UFO cover-up refers to the alleged suppression of information regarding unidentified flying objects (UFOs) during the presidency of Harry S. Truman (1945-1953). This theory suggests that Truman, along with other government officials, intentionally withheld knowledge of UFO sightings and related phenomena from the public. The term "UFO" translates to חפץ טייס לא מזוהה ( chafetz tayis lo mizuh) in Hebrew, OVNIs in Spanish, and UFOs or Unbekannte Flugobjekte in German. Key contextual information includes the establishment of the U.S. Air Force's Project Blue Book in 1952, which investigated UFO reports, and Truman's alleged involvement in classified discussions about extraterrestrial life. Skeptics argue that the lack of concrete evidence supports the idea of a cover-up, while proponents cite declassified documents and witness testimonies as proof of government secrecy. The Truman administration's handling of UFO-related information remains a subject of debate and speculation among researchers and enthusiasts.
