This image provided by The International Group for Historic Aircraft Recovery and displayed at a U.S. State Department news conference on Tuesday, March 20, 2012, may provide a new clue in one of the 20th century's most enduring mysteries and could soon help uncover the fate of American aviator Amelia Earhart, who went missing without a trace over the South Pacific 75 years ago, investigators said. Enhanced analysis of a photograph taken just months after Earhart's Lockheed Electra plane vanished shows what experts think may be the landing gear of the aircraft, the small black object on the left side of the image, protruding from the waters off the remote island of Nikumaroro, in what is now the Pacific nation of Kiribati. Armed with that analysis by the State Department, historians, scientists and salvagers from The International Group for Historic Aircraft Recovery, are returning to the island in July 2012 in the hope of finding the wreckage of Earhart's plane and perhaps even the remains of the pilot and her navigator Fred Noonan.
