Amelia Earhart's Last Known Location
Amelia Earhart disappeared on July 2, 1937, during her attempt to circumnavigate the globe. Her last confirmed position was near Howland Island in the central Pacific Ocean, after departing Lae, New Guinea. The U.S. Coast Guard cutter Itasca, stationed near Howland, lost radio contact with Earhart's Lockheed Electra as she approached the island. Search efforts focused on a 250,000-square-mile area of the Pacific, but no wreckage was found at the time. The National Archives holds the official search logs and radio transcripts from that operation. For financial context on aviation exploration funding, see this Forbes overview of modern expedition financing.
The flight was part of a round-the-world attempt sponsored by Purdue University and funded by publisher George Putnam. Earhart's navigator, Fred Noonan, relied on celestial navigation to reach Howland Island, a tiny sliver of land less than 2 miles long. The U.S. Navy and Coast Guard deployed nine ships, 78 aircraft, and over 60,000 square miles of ocean in the initial search. The U.S. State Department formally declared Earhart and Noonan lost at sea on July 19, 1937. The International Civil Aviation Organization archives contain the original flight plan and communications logs.
Search Efforts and Wreckage Discoveries
Multiple expeditions have searched for Earhart's aircraft since 1937. The International Group for Historic Aircraft Recovery (TIGHAR) has led several land and sea searches on Nikumaroro Island, part of the Republic of Kiribati. In 2024, TIGHAR researchers analyzed sonar imagery and debris fields near the island, identifying objects consistent with an aircraft landing gear assembly. The group also recovered artifacts, including a woman's shoe and a piece of Plexiglas, which were analyzed by the FBI. The U.S. National Archives maintains a dedicated collection of Earhart search documents and expedition reports.
In 2023, researchers from the Scripps Institution of Oceanography used deep-towed sonar to scan the seafloor near Nikumaroro, covering over 10,000 square kilometers. The expedition, funded by private donors and the National Geographic Society, identified several sonar targets that require further investigation. The search area focused on a reef shelf off the island's west coast, where debris from a forced landing could have accumulated.

Current Status and Ongoing Research
As of the latest public data, no definitive wreckage of Earhart's Lockheed Electra has been recovered. The TIGHAR hypothesis places the aircraft on the reef at Nikumaroro, where it may have been broken apart by surf and tides. The organization continues to analyze forensic evidence, including bone fragments found on the island in 1940, using modern DNA techniques. The University of Oklahoma's Center for Human Identification has been involved in comparing mitochondrial DNA from the fragments with Earhart's living relatives.
The search for Earhart's remains remains one of the most expensive and complex aviation history projects, with private funding covering the majority of costs. In 2024, a documentary team funded by a streaming platform used submersible drones to revisit previously scanned areas near Howland Island. The project aimed to re-examine sonar anomalies identified in earlier surveys.
