The Flying Saucers Are Real, by Donald Keyhoe, is a book that investigated reports of UFOs by United States Air Force fighters, personnel, and other aircraft, between 1947 and 1950.

Keyhoe contended that the Air Force was investigating these cases, with a policy of concealing their existence from the public until 1949.

Citing anecdotal evidence, he intimated the Air Force may have attained and adapted some aspect of the alien technology, its method of propulsion and perhaps its source of power.

He believed the Air Force or the United States federal government would eventually reveal these technologies to the public when the Soviet Union was no longer a threat.

"[5] A loose parody of Keyhoe's book and of reports of UFO sightings and alien abductions is The Flying Saucers Are Very Very Real (2016).
