Researchers say that a site in Papua New Guinea may contain the long-lost remains of Amelia Earhart's plane. Wreckage off the coast of Buka Island may offer a vital clue in the decades-long mystery, according to investigators from Project Blue Angel. The project's members have been studying the site for 13 years and say that wreckage off Buka Island could be from Earhart's Lockheed Electra 10E. Earhart famously disappeared while attempting to fly around the world. The aviator and her navigator, Fred Noonan, went missing on July 2, 1937, during a flight from Papua New Guinea to Howland Island in the Pacific. Their fate became one of the great mysteries of the 20th century and is still hotly debated here in the 21st. "The Buka Island wreck site was directly on Amelia and Fred's flight path, and it is an area never searched following their disappearance," said William Snavely, Project Blue Angel director, in a statement. "What we've found so far is consistent with the plane she flew."
