These 10 people didn't have greatness thrust upon them. They weren't born great. They faced challenges and prejudices and misconceptions. And despite it all, they chose to stretch the limits of what they could do, and in the process, they became truly exceptional.
Born in Kansas on July 24, 1897, aviation pioneer Amelia Earhart became the first woman to receive the U.S. Distinguished Flying Cross from Congress. The award was granted after she flew her Lockheed Vega from Newfoundland in Canada to Culmore in Northern Ireland in 1932 -- the first woman to fly solo across the Atlantic.
Earhart vanished over the Pacific in 1937 in a record attempt to fly around the world at the equator. Her final resting place remains a mystery. Meanwhile, researchers are scouring over data gathered during a deep-water search for her plane in the Pacific.
