The United States Air Force officially closed its investigation into unidentified flying objects (UFOs) known as Project Blue Book. This program began in 1952, aiming to assess UFO sightings and determine if they posed any threat to national security. After years of studies, the Air Force concluded that the majority of sightings were explainable and did not indicate extraterrestrial technologies. The decision to end the project reflected a shift in public and governmental interest regarding UFO phenomena.
