Amelia Earhart's Final Flight and Disappearance
Amelia Earhart disappeared on July 2, 1937, during her attempt to circumnavigate the globe. She was flying a Lockheed Electra 10E twin-engine aircraft. Her last confirmed radio transmission was received near Howland Island in the central Pacific Ocean. The flight departed from Miami on June 1, 1937, and had already completed most of the equatorial route. The disappearance occurred during the leg from Lae, New Guinea, to Howland Island. The U.S. Coast Guard cutter Itasca was stationed at Howland Island to guide her in. Despite clear weather reports, Earhart was unable to locate the island. Search efforts began almost immediately after her last transmission. The initial search covered a large area of the Pacific Ocean. It remains one of the most famous aviation mysteries in history. For more background on the flight, see this overview from the Smithsonian National Air and Space Museum Amelia Earhart.
The official search for Earhart was called off on July 19, 1937. The U.S. Navy and Coast Guard deployed ships and aircraft across the Pacific. The search area focused on a corridor between Lae and Howland Island. Despite extensive efforts, no wreckage or bodies were found. The search cost an estimated $4 million in 1937 dollars. It involved multiple vessels, including the USS Colorado and USS Astoria. The search area was later expanded based on revised radio direction-finding data. The official report concluded that Earhart and her navigator, Fred Noonan, were lost at sea. The case was closed by the U.S. government. However, private expeditions have continued to search for evidence. The disappearance has generated decades of speculation and research. More details on the official search can be found in the National Archives Amelia Earhart Records.
Search Efforts and Latest Findings
Modern searches have used advanced technology to locate Earhart's aircraft. Sonar scans and underwater drones have explored the ocean floor near Howland Island. In 2019, a private expedition used deep-sea sonar to search a specific area. The search focused on a reef slope near Nikumaroro Island. The team found an object that matched the size and shape of a Lockheed Electra landing gear. Further analysis was inconclusive. Other expeditions have searched Nikumaroro Island itself. Bones found on the island in 1940 were reanalyzed in 2018. A forensic study suggested the bones were consistent with Earhart's height and build. The study was published in the journal Forensic Anthropology. The International Group for Historic Aircraft Recovery (TIGHAR) has led many of these efforts. They continue to analyze artifacts and oral histories from the island. For more on the latest forensic analysis, see this report from the Smithsonian Amelia Earhart Bones.
Satellite imagery and underwater mapping have also been used in recent years. Companies like Ocean Infinity have conducted extensive seabed surveys. These surveys use autonomous underwater vehicles to map large areas. The data is analyzed for anomalies that could be aircraft wreckage. Some researchers have proposed that Earhart's plane landed on a reef near Nikumaroro. Tidal action could have moved the wreckage into deeper water. The theory is supported by artifacts found on the island, including a woman's shoe and a dating cream jar. The jar was from a brand produced in the 1930s. The search for Earhart's plane remains active. New technologies continue to improve the chances of discovery
