"The Report on Unidentified Flying Objects" by Edward J. Ruppelt is a book published in 1956. Written by the former director of the Air Force's Project Blue Book, it reveals the inside story of official UFO investigations from 1947 onwards. Ruppelt details mysterious sightings near atomic facilities, radar contacts, pilot encounters, and the controversial "Estimate of the Situation" report that concluded some UFOs were interplanetary craft—only to be officially rejected.
