On July 2, 1937, near the end of her pioneering flight around the world, Amelia Earhart vanished somewhere over the Pacific Ocean. Most experts, including the Smithsonian’s Air and Space Museum, believe Earhart likely ran out of fuel and crashed into the Pacific Ocean. But no trace of the aviator, navigator Fred Noonan or her twin-engine Lockheed Electra airplane were ever found, confounding historians and fueling conspiracy theories ever since.
