17 Researchers Sail to Nikumaroro in Search for Earhart's Plane

A 17-person expedition of U.S. researchers has sailed for Nikumaroro, an uninhabited coral atoll in the Pacific nation of Kiribati, to determine whether a submerged object in its lagoon is the wreckage of Amelia Earhart's Lockheed Model 10-E Electra, according to the Guardian.

Earhart and her navigator, Fred Noonan, disappeared in 1937 while attempting to circumnavigate the globe along the equator. The expedition, funded in part by Purdue University — Earhart's former benefactor — is the latest attempt to resolve what the Guardian calls one of the biggest mysteries of the 20th century.

Where is Nikumaroro and why does it matter?

Nikumaroro sits roughly halfway between Australia and Hawaii, part of the Kiribati archipelago. Researchers have long floated the hypothesis, still unproven, that Earhart and Noonan ditched their twin-engine aircraft at the atoll rather than crashing elsewhere in the Pacific. Locating the wreck there would confirm that theory, according to the Guardian's reporting.

What evidence points to a submerged object there?

The expedition was inspired by satellite images taken over several years showing a submerged object in the atoll's sandy lagoon. A 2001 satellite image of Nikumaroro is among the visual records cited. Separate aerial footage of the area, according to the team, suggested the object has a metallic glint — a detail they say strengthens the case that it could be the Electra rather than natural debris.

Data points

• 1937: Year Earhart, then 39, and Noonan vanished during their round-the-world attempt.
• 17: Number of researchers on the current expedition to Nikumaroro.
• 2001: Year of a cited satellite image showing the atoll and the submerged object in its lagoon.

Who is leading the expedition, and why do skeptics disagree?

The expedition is led by archaeologist Richard Pettigrew. Speaking before setting sail this month, Pettigrew framed the stakes in stark terms.

"Finding Amelia Earhart's Electra aircraft would be the discovery of a lifetime. Confirming the plane wreckage there would be the smoking-gun proof."

Not every longtime Earhart researcher shares that optimism. According to the Guardian, other sleuths who have studied the case for years dismiss the satellite evidence, arguing the submerged object is probably a fallen tree rather than an aircraft fuselage. The dispute underscores how contested the Nikumaroro hypothesis remains even among specialists who have spent decades on the case — the Guardian's reporting notes a separate claim, since discredited by a blogger, that Earhart had instead been taken prisoner by Japan.

What did Earhart attempt before she vanished?

By 1937, Earhart was already a celebrity and aviation pioneer. She had set multiple records, including becoming the first woman to complete a nonstop solo transatlantic flight, according to the Guardian. Her attempt to circumnavigate the globe at the equator was intended to add to that record before she and Noonan disappeared over the Pacific.

What happens next?

The 17-person team's approach to Nikumaroro marks the active phase of the search: divers and researchers will attempt to examine the submerged object directly rather than rely solely on satellite and aerial imagery. Whether the mission produces conclusive identification — plane or tree — remains to be seen, and the Guardian's account makes clear that skepticism from rival researchers will persist regardless of what the team reports from the lagoon.

Glossary

• Atoll: A ring-shaped coral reef or series of islets surrounding a lagoon, often with little or no permanent population — Nikumaroro is uninhabited.
• Electra (Lockheed Model 10-E): The twin-engine aircraft Earhart and Noonan flew on their 1937 circumnavigation attempt.
• Archipelago: A chain or cluster of islands; Nikumaroro is part of the Kiribati archipelago in the central Pacific.

What is Purdue University's connection to Earhart?

Purdue University's involvement is not incidental. The Indiana school served as Earhart's benefactor during her lifetime, and researchers leading the current expedition raised funding from the university to mount the search, according to the Guardian. That institutional backing, decades after Earhart's disappearance, reflects how her case has remained tied to the university long after her final flight, and it is one reason the team's archaeologists — rather than independent hobbyists — are the ones now approaching Nikumaroro's lagoon.
