Curiosidades

Against the director's expectations, authorization was received to film a sequence where an unmarked all-black T-33 was fleeing at low-altitude over Paris to avoid radar. The production crew were limited to three passes by the unidentified aircraft over the Seine; in case of mishap, the plane would crash in the water, rather than on the city. The scene caused panic as people on the ground feared a genuine attack was taking place.

The final credit titles' song is sung by Johnny Hallyday, one of the greatest rock'n roll singer in France.

The Voltaire (supersonic VTOL prototype) seen in the show did really exist under the name of Balzac (both names are famous French authors' names). So special effects weren't required when it's shown hovering.

The French Air Force provided extensive access to its facilities and equipment. Most ground action was shot at Dijon fighter base, using military personnel as extras.

The TV series "Les Chevaliers du Ciel" is based upon a series of comics "Les Aventures de Tanguy et Laverdure", that's probably why these two names are mentioned in the credit titles: "Dans la série 'Les Aventures de Tanguy et Laverdure'... Les Chevaliers du Ciel..." (In 'The Adventures of Tanguy and Laverdure' series... The Sky Knights...").
