Continuity: The film is supposed to take place in 1917, but several of the german soldiers our heroes encounter are armed with Bergman M18 sub-machineguns which didn't appear until a year later. To make things even worse all the guns comes with a magazine-type that didn't appear until the mid-thirties.
Factual error: In 1986, Jim Ferguson hands William Raymond the film that Biggles took in 1917 and when he and Biggles return the next day the film has been developed and has even had computer enhancement. Given the technology of the mid 80's, I simply find it hard to believe that the film could have been developed that quickly (even today, it would still take longer than one night).
