Henry B. Walthall, who plays "Dad" in the film, collapsed on the set and died shortly thereafter. The film was made with the cooperation of Pan American Airlines and is loosely based on the history of that company, which used the name "Clipper Ships" for its planes. Modern sources add the following credits: Pilot, Paul Mantz; Aerial photography, Elmer Dyer and H. F. Koenekamp.
