Road Pirates - S2-E5
Factual error: When Roscoe tries the same jump the Dukes did, his car goes nose first into the wall of the ravine. Upon a close up, Roscoe is fine, but not wearing a seatbelt. According to physics, he should go through the windshield or get cut up.
Factual error: The real RAF chief meteorologist was Group Captain Stagg. For some reason, he is the only character in the series who has been fictionalised, as Captain Burns. However Captain is not an RAF rank. Unlike the fictional Burns, Stagg was not a pilot and had no medal ribbons (he had no previous military service before receiving a war commission for his meteorological skills).
