For some reason, in 1943, West Virginian coal miner Emilio Franco lost his ability to speak. He remained mute, and doctors could not find any medical reason for his lack of speech. It turns out that all Franco needed was a ride on a roller coaster.
In 1949, six years after his initial silence, Franco rode the Coney Island Cyclone coaster with his cousin. The coaster was incredibly popular. It featured an 85 ft drop and was advertised as "The Most Fearsome Coaster Ever Built." With frequent riders, it paid off it's $100,000 cost in just one year. When Franco stumbled off the ride, his first words in years were "I feel sick."
