Amelia Earhart was an American aviator who set many flying records and championed the advancement of women in aviation. She became the first woman to fly solo across the Atlantic Ocean, and the first person ever to fly solo from Hawaii to the U.S. mainland. During a flight to circumnavigate the globe, Earhart disappeared somewhere over the Pacific in July 1937. Her plane wreckage was never found, and she was officially declared lost at sea. Her disappearance remains one of the greatest unsolved mysteries of the twentieth century.
