Scientists are attempting to create a genetic profile for Amelia Earhart through her saliva - taken from letter seals - to determine if a bone fragment found in 2009 does belong to the missing aviator.
In July 1937, Amelia Earhart and her navigator, Fred Noonan, vanished over the Pacific Ocean. Using the Equator, they were attempting to fly around the world, one of the longest routes around the Earth. She was the first woman to fly solo across the Atlantic Ocean. (See 10 famous disappearances.)
