Other mistake: At the two-hour point when Terry-Thomas' plane lands on the moving train a nuclear power plant can be seen in the background several times. (02:04:38 - 02:05:02)
Other mistake: The Japanese plane and the German plane are actually the same aircraft type, a British Design called an "Eardly Billing." The "Japanese" version is re-dressed with canvas partitions between the wings, painted dragons, etc, the "German" has no canvas and German eagles, but they are the same machine.
Other mistake: As the planes go over Dover you get a very nice view of the modern harbour complete with cross Channel ferries and oil tanker.
Other mistake: When Stuart Whitman asks to borrow a monkey wrench from James Fox, Fox hands him a pipe wrench, a very different tool.
Suggested correction: This is not a mistake for two quite plausible reasons. First, the two flyers are the principal rivals in the race and it would be quite in character for one to try to impede the other by substituting a tool inferior to the one requested. Second, the Monkey wrench and the Pipe wrench are similar in appearance and function. The pipe wrench may have worked. Also, Wikipedia says: The term monkey wrench is also sometimes used loosely, usually by non-tradespeople, to refer to the pipe wrench."
