Amelia Earhart

Case background and investigation

Amelia Earhart, already the first woman to fly solo across the Atlantic, set out in 1937 to become the first woman to circumnavigate the globe by air. Flying a twin-engine Lockheed Electra 10E with navigator Fred Noonan, she departed Oakland, California, on May 20, 1937, on an eastbound route. Over the following weeks the pair hopped across the Caribbean, South America, Africa, South Asia and Southeast Asia, and by June 29, 1937, they reached Lae, New Guinea, having covered roughly 22,000 of the planned 29,000 miles.

The most demanding stretch remained: a flight of about 2,500 miles from Lae to Howland Island, a flat sliver of coral in the central Pacific barely visible from the air. Success depended on Noonan's celestial navigation and on radio contact with the U.S. Coast Guard cutter Itasca, stationed off Howland to guide them in. Earhart and Noonan left Lae on July 2, 1937. As the flight neared its destination, Itasca received a series of voice transmissions in which Earhart reported she was 'running low on gas' and, in a final message, described flying along a 'line of position 157 337.' The aircraft was never seen again.

The disappearance triggered what was then the largest and most costly air and sea search in U.S. history, involving Navy and Coast Guard ships and aircraft, including the battleship USS Colorado and the carrier USS Lexington, sweeping roughly a quarter-million square miles of ocean. The search was called off around July 18-19, 1937, having found no trace of the plane or its crew. Earhart was declared legally dead in absentia on January 5, 1939.

No explanation has ever been confirmed, and several competing hypotheses remain in circulation. The 'crash-and-sink' theory, favored by the U.S. Navy at the time and by many researchers since, holds that the Electra exhausted its fuel and ditched in deep water near Howland, sinking with little trace. A rival 'castaway' hypothesis, advanced most prominently by The International Group for Historic Aircraft Recovery (TIGHAR) and its director Ric Gillespie, argues that Earhart and Noonan followed their line of position south to uninhabited Gardner Island (now Nikumaroro), landed on the reef flat and died as castaways. Proponents point to bones found on Nikumaroro in 1940; an examination by physician D.W. Hoodless in 1941 judged them to be a male's, while a 2018 reanalysis by anthropologist Richard Jantz argued the measurements were consistent with Earhart. A separate theory that the pair were captured by Japanese forces is dismissed by most historians as lacking credible evidence. Each account remains an unproven hypothesis.

Modern expeditions continue to test these ideas with sonar, forensic and archaeological methods. In January 2024 the firm Deep Sea Vision released a sonar image of a plane-shaped anomaly roughly 100 miles from Howland, but after revisiting the site the team announced in November 2024 that the object was a natural rock formation, not the Electra. Attention has also turned to the 'Taraia Object,' an anomaly in Nikumaroro's lagoon that researchers from the Archaeological Legacy Institute and Purdue University planned to examine on expeditions in 2025 and 2026. As of 2026, none of these efforts has produced confirmed wreckage, and the fate of Amelia Earhart and Fred Noonan officially remains unsolved.
