Location photography included scenes at a desert airfield near Victorville, California, Kauai and Waikiki Beach, Hawaii, with interiors shot at the Disney Studios sound stages. The scrapped airframes from four B-29 aircraft that were located at the US Navy's China Lake Facilities were used. Two of the scrapped aircraft were used in Hawaii, while the other two were shipped to the Burbank studio for interiors. Extensive modifications were made in order to have a fuselage that could float. After filming, all the aircraft remains had to be returned to the US Navy. One additional aircraft, the former US Navy P2B-1S long-range-search version of the B-29 Superfortress, named "Fertile Myrtle", actually flew in the film.
