It was 1940, and the German Luftwaffe was making regular air raids on the United Kingdom. Although the British Royal Air Force was successful in shooting down many German planes, blackouts were still in effect across the country to minimize the visibility of targets on the ground. But don’t worry, the British government said. If you eat carrots, they’ll help you see in the dark, just like they did for RAF Flight Lieutenant John “Cat’s Eyes” Cunningham. Cunningham was responsible for shooting down 20 German aircraft, and it was attributed to his love of carrots. The only problem with that? The British government made it up.
