Project Blue Book: The US Air Force’s UFO investigations, findings, and closure (1947–1969)
To the point
Project Blue Book was the US Air Force’s investigation from 1952 to 1969, led by Major General Charles P. Cabell, to study thousands of UFO sightings, most of which were explained with 701 remaining unidentified, and it ended after the Condon Committee with redacted files released later.
