The UCLA Film and Television Archive restored the film to its premiere version, which is the version currently available on DVD. In addition to reinstating the 8-minute two-strip Technicolor sequence, tinting and toning was restored to the duel at sunrise, the Zeppelin battle, the night patrol, and Monte and Roy departing for their bombing run. Note that these sequences were intact on earlier prints, but without color or special processing. The film's Intermission title card, along with Entr'acte music and exit music were reinstated as well.
Original British version was heavily edited (over 30 min.) to gain an A rating.
