An advertisement in the 12 Feb 1966 LAT listed filmmaker-clergyman Dr. Frank Stranges, Ph.D., as an “authority on flying saucers.” The 20 Jun 1966 LAT revealed that the title of the picture was derived from a U.S. Air Force report, which estimated that nearly eight percent of all unidentified flying object (UFO) sightings defied explanation. The article went on to say that Stranges became interested in UFOs years earlier, after his college roommate, a former a U.S. Marines flyer, claimed to have seen one. Location sequences were filmed in Brazil and Socorro, NM, the site of a 1964 UFO landing witnessed by police sergeant Lonnie Zamora, who recounted the event on screen. The production was assisted by Ewing Brown of Movie Tech Studio.
       The 25 Apr 1965 Alamogordo Daily News (NM) reported that Empire Film Studios, based in Los Angeles, CA, had tentatively planned a premiere in Socorro. The local newspaper, El Defensor Chieftain, printed a letter from producer Michael Musto, assuring Socorro Mayor Holm O. Borsum, Jr., that the recently-completed picture would reach a worldwide audience. Socorro officials anticipated a wave of tourism following the release, but they were ultimately disappointed, as the filmmakers were unable to secure adequate distribution.
       According to the 30 May 1966 LAT, the official premiere was scheduled for the Wilshire Ebell Theater in Los Angeles, CA, on 17 Jun 1966, with additional showings to follow. On 20 Jun 1966, LAT reported that a local film laboratory accidentally delivered the print to a major aircraft company. After passing the print through several departments, bewildered employees assumed it contained classified information and stored it in a vault. Movie Tech eventually retrieved the print and the screening proceeded on schedule.
       A review in the 13 Jul 1966 Cedar Rapids, IA, Citizen Times described the documentary as well-constructed but lacking in “any scientific basis.” Interviewees included television journalists, military personnel, scientists, and eye-witnesses. The 12 Aug 1966 LAT stated that the ninety-minute film was the culmination of twenty years of research. Other sources list the running time as seventy minutes.
       Dr. Stranges went on to establish the National Investigations Committee on Unidentified Flying Objects (NICUFO), and wrote several books on extraterrestrial sightings.
