This behind-the-scenes documentary is included on Disc 2 of the 2-disc Paramount Home Entertainment Special Collector's Edition (The John Wayne Collection) DVD of The High and the Mighty (1954).
In the DVD menu, the "Flying in the Fifties" segment is a separate entry on the same level as "The Making of The High and the Mighty", and many DVD review sites consider it a separate featurette. IMDb includes it as part of "The Making of..." for two reasons: 1) Its credits are combined with the other segments' credits in a closing-credits chapter at the end of this documentary, accessible only from the "Play All" menu selection; and 2) Leonard Maltin's introduction: "A segment we're calling 'Flying in the Fifties'..." implies that it is part of this documentary.
