Purdue-Led Expedition Finds No Sign of Earhart's Plane in Pacific Lagoon

A seven-day search of a remote Pacific lagoon has ended the way skeptics predicted it would: with trees, not airplane wreckage.

Purdue University and the Archaeological Legacy Institute said Sunday that their long-delayed expedition to Nikumaroro, an uninhabited coral atoll in the Pacific nation of Kiribati, found "no conclusive evidence" that the so-called Taraia Object — a shape first spotted in 2020 satellite imagery of the island's lagoon — is any part of Amelia Earhart's missing Lockheed Electra 10-E. The team's own account of the dig, posted to Purdue's newsroom, said the anomaly was most likely "a collection of large trees deposited along the peninsula's sandspit," most of which had already broken apart and washed away by the time researchers reached the spot.

It is the latest reversal in a search that has run, on and off, for nearly 90 years.

What the team found, and didn't

The 17-member expedition, organized jointly by the nonprofit Archaeological Legacy Institute (ALI) and the Purdue Research Foundation, launched from Tarawa, Kiribati, on October 6 and spent five days at sea reaching Nikumaroro. According to the expedition's official project site, the crew began an underwater survey of the lagoon on October 14 using a magnetometer and side-scan sonar, then moved to hands-on inspection with a hydroprobe and water-injection dredge once they located the target area.

What they found was far smaller than what satellites had recorded six years earlier. Researchers located a single Y-shaped segment of debris — a fraction of the original anomaly — coated in a hardened veneer of coral sand that gave it the reflective, metallic look that had fueled speculation it was fuselage. It was not metal. Divers also recovered a steel tube roughly 30 inches long from the lagoon near the peninsula, along with other sand-concretized debris, which researchers plan to study further on the theory that objects can drift into the area through a nearby channel known as the Tatiman Passage.

Severe weather cost the team three of the seven days they had budgeted for fieldwork, limiting them to four days onshore before fuel and supply constraints forced a return to Tarawa.

Nearly 90 years of searching

Earhart and navigator Fred Noonan disappeared on July 2, 1937, while attempting to fly around the world, after departing Lae, New Guinea, for tiny Howland Island. They were never found, and the United States government's official position has long been that the Electra went down in open ocean. Since the 1980s, a rival theory — developed by The International Group for Historic Aircraft Recovery (TIGHAR) and later adopted by ALI — has held that the pair instead missed Howland, turned south, and put the plane down on Nikumaroro's reef flat, where they survived for a time as castaways before dying.

That "castaway hypothesis" rests on a patchwork of circumstantial evidence gathered over decades of prior expeditions: 1930s-era artifacts recovered on the island, including a woman's shoe, a compact case and a freckle-cream jar; bones found in 1940 and identified at the time as likely male, then lost before modern DNA testing was possible; radio bearings taken in the days after the disappearance; and a 1937 photograph of the island's shoreline, known as the Bevington Object, that some researchers believe shows a protruding piece of the Electra's landing gear.

The Taraia Object entered that story in 2020, when a satellite image showed an unexplained shape beneath the lagoon's surface. ALI's executive director, Rick Pettigrew, had argued publicly before the expedition that the evidence pointing to an aircraft was "very strong." Not everyone agreed. Ric Gillespie, TIGHAR's own executive director and a longtime rival in the Earhart research community, told Reuters ahead of the trip that he expected the opposite result, arguing the object's "root ball" and "branches" were visible even in the satellite imagery, as he told the Australian broadcaster SBS. "People see what they want to see," Gillespie said.

The expedition's path to Nikumaroro was itself delayed nearly a year. ALI and Purdue announced the project in mid-2025, aiming for a November 2025 departure, but could not secure the necessary permits from the Kiribati government in time and pushed the trip back to October 2026, also avoiding the Pacific's cyclone season.

Who is invested in the answer

The search carries particular weight at Purdue, where Earhart worked in the 1930s as a visiting faculty member and adviser to the university's aeronautics program. The Purdue Research Foundation helped finance her Electra, and Earhart had told colleagues she intended to donate the plane back to the university after completing her circumnavigation. That history is why Purdue's involvement goes beyond academic curiosity: university officials have said that definitively identifying the aircraft's remains would be a first step toward eventually bringing it home to West Lafayette, Indiana.

Steve Schultz, Purdue's general counsel, flew with the team as a field assistant and was one of two officials who signed the results statement alongside Pettigrew. The expedition was funded in large part by private donors, along with corporate sponsors including Columbia Sportswear, DHL Express and Fiji Airways, and logistical support from the governments of Kiribati and the United States embassy covering the region.

For the broader community of Earhart researchers and enthusiasts — a mix of historians, aviation buffs and amateur sleuths who have sustained interest in the case for generations — the result extends, rather than resolves, a debate that has outlasted several of its original participants. The Smithsonian's National Air and Space Museum has historically urged caution about Nikumaroro claims, and the federal government has not altered its own account of the disappearance.

What researchers are saying

Despite the negative result on the Taraia Object itself, Pettigrew framed the expedition as a success on its own terms. "We accomplished our goal to determine what the Taraia Object was," he said in the statement, thanking the private donors who financed the trip and adding that the team "remains in great spirits and proud of what was accomplished."

"Perhaps no words better capture this expedition than Amelia Earhart's own: 'Adventure is worthwhile in itself.' We set out to test a hypothesis, not to guarantee a particular result, and we followed the evidence to the end," said Steve Schultz, Purdue's general counsel and a member of the expedition team.

Schultz added that while "the Taraia Object did not prove to be what we hoped, the journey produced new discoveries" that "added to the world's knowledge of Nikumaroro." Both men said the broader castaway hypothesis remains intact in their view, even without a confirmed piece of the aircraft. Earlier coverage of the expedition's approach, including by Newsweek and CBS News, tracked the team's progress across the five-day sea crossing and the weather delays that cut into its time on the atoll.

What happens next

Purdue has said it intends to keep searching, though no new expedition has been scheduled. The steel tube and other artifacts recovered from the lagoon will undergo further analysis, researchers said, partly to test whether debris genuinely can travel from elsewhere in the lagoon system to collect on the Taraia Peninsula — a mechanism that would help explain what the satellite anomaly actually was, independent of Earhart's disappearance.

The outcome leaves the core Nikumaroro theory exactly where it has stood for years: unproven, but not abandoned, by a research community that has absorbed disappointing expeditions before. ALI's own project pages, including its Taraia Object research page, continue to list the broader castaway hypothesis as the group's working theory.

Separately, the expedition's result arrives against the backdrop of a 2025 directive from President Trump ordering federal agencies to declassify and release government records related to Earhart's disappearance, a process that has already produced batches of newly public FBI and National Archives material but has not altered the official federal account that the Electra was lost at sea. Whether any of those records bear on Nikumaroro, or on the Taraia Object specifically, remains to be seen as the declassification process continues.
