A high-profile search for Amelia Earhart’s long-lost aircraft in the South Pacific has ended without finding wreckage, researchers announced, dealing another setback to solving one of history’s most enduring aviation mysteries.
A 17-member expedition organized by Purdue University and the Oregon-based Archaeological Legacy Institute journeyed to the uninhabited coral atoll of Nikumaroro in the Republic of Kiribati. The team sought to examine the “Taraia Object,” an anomaly first detected in 2020 satellite photos lying in a shallow lagoon off the atoll’s Taraia Peninsula. Organizers had suspected the shape could be debris from Earhart’s twin-engine Lockheed Electra 10-E aircraft.
Instead, investigators discovered the shape was an accumulation of fallen timber coated in shiny minerals, Purdue University announced in a statement. Most of the debris had broken apart and drifted away before the team arrived, leaving behind only a single Y-shaped piece of wood that represented a fraction of the mass originally observed.
“The fragment’s reflective surface, long associated with the idea that the object was a metallic substance, was due to its carbonate veneer,” the university said. Researchers noted other natural objects in the vicinity were similarly encrusted with a hardened mix of coral sand.
Challenging conditions in the South Pacific
Reaching the remote atoll required a five-day sea voyage from Tarawa, Kiribati’s capital. Once on site, the team faced harsh circumstances. Rough weather confined searchers to their vessel for three of the five scheduled search days, CBS News reported, while fuel limits prevented extending the mission. On land, the crew set up tents for four days of field study but slept offshore, in part because the island is populated by massive coconut crabs.
“Unfortunately, we weren’t able to find that smoking gun,” said Steve Schultz, Purdue’s general counsel and an expedition participant, standing on the shoreline in video remarks.
Earhart and navigator Fred Noonan disappeared on July 2, 1937, during their attempt to complete an equatorial circumnavigation of the globe. The pair vanished on an 18-hour leg between Lae, New Guinea, and Howland Island, an isolated U.S. territory roughly 400 miles northwest of Nikumaroro. Despite the largest air and sea search undertaken by the U.S. government at the time, no trace of the plane was verified.
The enduring castaway debate
The official consensus remains that Earhart and Noonan ran out of fuel and plunged into the deep ocean near Howland Island. However, alternative theorists maintain the pair navigated south along a navigation line, crash-landed on Nikumaroro’s flat reef, and lived briefly as castaways.
Past expeditions to Nikumaroro documented artifacts, including 1930s-era glass jars, parts of a woman’s shoe, and human bones that were collected during the colonial era but later misplaced. During the latest trip, researchers surveyed the lagoon bed with sonar gear and magnetometers, collecting several items including a 30-inch steel tube for laboratory examination.
Richard Pettigrew, executive director of the Archaeological Legacy Institute, emphasized that disproving the Taraia Object anomaly does not dismantle the broader theory.
“We accomplished our goal to determine what the Taraia Object was, and we’re deeply grateful to the private donors who shared our vision,” Pettigrew said. “The evidence for the castaway hypothesis, which brought us here, remained very, very strong.”
Other aviation historians remain skeptical. Dorothy Cochrane, an Earhart specialist and retired curator at the Smithsonian National Air and Space Museum, told CNN that Nikumaroro has been examined more than 15 times without providing authenticated evidence of Earhart, Noonan, or their Electra.
Previous technological leads have similarly dissolved upon closer inspection. In 2024, ocean exploration firm Deep Sea Vision published sonar data showing an airplane-like silhouette on the ocean floor near Howland Island, but subsequent analysis revealed it to be natural rock.
Private exploration groups continue planning future missions. Marine company Nauticos is seeking up to $10 million to fund another sonar survey in the deep ocean around Howland Island, hoping modern radio modeling can finally pinpoint the aircraft’s resting place.
