Former U.S. Marine Caroline Schreiner, the second contestant, was a Federal Aviation Administration's (FAA) air traffic controller at the Hutchinson Municipal Airport tower, in Kansas. Women had entered the ranks of air traffic controllers and aircraft communicators since 1941, to replace men who joined the WWII effort.
Richard Chamberlain and Raymond Massey had played the characters 'Dr. Kildare' and 'Dr. Gillespie' in the original never-aired pilot episode for the psychiatric medical drama series 'The Eleventh Hour (1962)'. In the story, both doctors assist "Dr. Theodore Bassett" (a psychiatrist character played by Wendell Corey) in diagnosing patient Ann Costigan (played by guest star Vera Miles). The episode was initially meant to air as an episode of 'Dr. Kildare (1961)' but was instead reworked to cut out Chamberlain and Massey's parts and remove all Kildare and Gillespie references before airing on October 3, 1962, as the debut episode of the new TV series, entitled "Ann Costigan: A Duel on a Field of White (1962)".
