 In order to film the aerial sequences, footage was leased from Howard Hughes and one scene was directly lifted from "Hell's Angels" (1930), which had been Harlow's break-through film.A number of aircraft were prominently seen, including Andre's S.E.5 fighter, German Fokker D.VII and Thomas-Morse S-4 fighters as well as a rare Sikorsky S-29-A airliner filling in as a German Gotha bomber.Although Harlow dominates the film, it is not considered one of her finest, with a mundane plot and only the Grant and Tone roles being notable.
