In this photo supplied by the International Group for Historic Aircraft Recovery, the South Pacific atoll of Gardner Island, now called Nikumaroro, is seen from the air on July 9, 1937. This is where some believe Amelia Earhart survived as castaway in 1937. The photo shows the central lagoon and surf flowing over a flat reef on the shoreline where Earhart may have crash-landed after missing her planned destination.
This photo supplied by the International Group for Historic Aircraft Recovery is the only known picture of Earhart's Lockheed Electra taking off from Lae, New Guinea on July 1, 1937, for the 2,550-mile flight to Howland Island. The plane's radio reception antenna, ripped off on the primitive runway, is already missing in photo. Associated Press
Famed aviator Amelia Earhart and her navigator, Fred Noonan, pose in front of their twin-engine Lockheed Electra in Los Angeles at the end of May, 1937, prior to their historic flight in which Earhart was attempting to become first female pilot to circle the globe. A clear plastic shard found on Nikumaroro island in 1977 matches the thickness and curvature of the Lockheed Electra windows.
This undated photo provided by the International Group for Historic Aircraft Recovery shows a page from the school composition notebook in which 15-year-old Betty Klenck recorded words from distress calls she heard over her short-wave radio in July 1937. Now 84, she is certain the voice she heard was Amelia Earhart, marooned on a small South Pacific island.
