Corrected entry: 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).

Correction: Minilabs, which can develop film in less than an hour, were available in the late 70's. By the mid-80's many stores offered one-hour photo. The reason it took overnight (or longer) for film to be developed during the 80's was because the processing labs were off-site and the film had to be delivered, processed (with thousands of other orders), then delivered back. So actually developing the film doesn't take a whole day.
