The film was released by Buena Vista Distribution on June 25, 1980.  A full-scale Boeing B-29 Superfortress bomber was featured in the film as the "ark".

Birth of the B-29: Birth of the B-29 was a 1945 propaganda film commissioned by the US War Department.  As the name implies, it concerned the production of the B-29 Superfortress bomber and its use in the aerial bombing of Japan in World War II.

Enola Gay: The Enola Gay ( ) is a Boeing B-29 Superfortress bomber, named for Enola Gay Tibbets, the mother of the pilot, Colonel Paul Tibbets, who selected the aircraft while it was still on the assembly line.  On 6 August 1945, during the final stages of World War II, it became the first aircraft to drop an atomic bomb.  The bomb, code-named "Little Boy", was targeted at the city of Hiroshima, Japan, and caused unprecedented destruction.  "Enola Gay" participated in the second atomic attack as the weather reconnaissance aircraft for the primary target of Kokura.  Clouds and drifting smoke resulted in a secondary target, Nagasaki, being bombed instead.

Allophone (Quebec): In Quebec, an allophone is a resident, usually an immigrant, whose mother tongue or home language is neither French nor English.  The term can also be sometimes used in other parts of Canada.  The term parallels "Anglophone" (English-speaker), and "Francophone", which designate people whose mother tongues are English and French, respectively.  Native speakers of aboriginal languages are generally not treated as allophones.

1948 Waycross B-29 crash: The 1948 Waycross B-29 crash occurred on 6 October 1948 when an engine fire contributed to the crash of a Boeing B-29-100-BW Superfortress bomber in Waycross, Georgia.  The plane was from the 3150th Electronics Squadron, United States Air Force and had tail number 45-21866.  The crash occurred during climb to altitude from Robins Air Force Base and killed nine of thirteen men aboard, including three RCA engineers.  Four men parachuted to safety.  Because the flight was a test of the "sunseeker" (a heat-seeking device later used in the AIM-9 Sidewinder missile), the Federal government asserted the state secrets privilege to avoid having to provide the NTSB accident report in a subsequent suit for damages by victims of the crash and their heirs, despite the device playing no role in the crash itself and not being referred to in the report.

Silverplate: Silverplate was the code reference for the United States Army Air Forces' participation in the Manhattan Project during World War II.  Originally the name for the aircraft modification project which enabled a B-29 Superfortress bomber to drop an atomic weapon, "Silverplate" eventually came to identify the training and operational aspects of the program as well.  The original directive for the project had as its subject line "Silver Plated Project" but continued usage of the term shortened it to "Silverplate".
