The disappearance of Amelia Earhart is probably the most well-known mystery in the world that doesn't involve Tom Hanks looking for clues in old paintings. In 1936, Earhart planned to reserve herself a page in the record books by flying around the world; a 29,000-mile journey. On the last 7,000-mile leg of her second attempt in 1937, she disappeared after giving her last radio transmission. The transmission was not anything helpful like, "I'm going to try to just fly through this mountain. I saw it in a cartoon once."
More has been speculated about her disappearance than has probably been written about her life. One of the more epic theories is that Earhart and her navigator, Fred Noonan, went down over part of the Japanese Empire and were captured, interrogated as spies and executed. Some assert that she was actually a spy for President Roosevelt, and that she secretly lived to the end of her days in New Jersey. Still others, with less imagination, think that she deliberately flew her plane into the Pacific because f**k it.
