Amelia Earhart was the most famous female pilot in history. She was breaking the glass ceiling decades before anybody had coined that term. In the 1920s and 1930s she was setting records - not just for women, but for everybody. In 1937, she and her navigator Fred Noonan tried to circumnavigate the Earth.
