A team of U.S. researchers has embarked on an expedition to the remote Pacific atoll of Nikumaroro, part of the island nation of Kiribati, aiming to uncover new evidence related to the disappearance of famed aviator Amelia Earhart and her navigator Fred Noonan in 1937.

The 17-person mission, led by archaeologists associated with the Archaeological Legacy Institute and supported by Purdue University in Indiana, seeks to investigate a submerged, plane-shaped object in the sandy lagoon of the uninhabited atoll. Satellite images taken over several years first revealed the elongated shape, which the team refers to as the "Taraia Object" after the area of its discovery. Additional aerial footage has been reported to show a metallic glint on the object, raising hopes that it may be the remains of Earhart’s Lockheed Model 10-E Electra aircraft.

Earhart and Noonan vanished during their attempt to circumnavigate the globe along the equator. At the time, Earhart was an aviation pioneer and celebrity, known for being the first woman to make a nonstop solo transatlantic flight. The pair were en route to Howland Island, located approximately 400 miles north of Nikumaroro, when their plane ran low on fuel and disappeared.

The expedition follows a six-day sea voyage from Tarawa, Kiribati’s capital, with plans to spend several days exploring the lagoon for the submerged object. Researchers involved in the mission believe the plane wreckage could have gone undetected in previous searches due to sand coverage.

However, this interpretation is not universally accepted. The International Group for Historic Aircraft Recovery (Tighar), a U.S. exploration group that has conducted multiple expeditions to Nikumaroro since 1989, offers a different perspective. Ric Gillespie, Tighar’s co-founder and a leading Earhart researcher, contends that the so-called Taraia Object is likely a dead pandanus tree native to the region that washed into the lagoon. Gillespie noted that previous visits to the site in 2001 and 2007 included the use of metal detectors, but no aircraft material was found.

While Tighar concurs that Earhart and Noonan made an emergency landing on Nikumaroro, they argue that the plane was likely washed off a reef and now rests in broken pieces in deeper waters off the island’s western coast. The group also advances the theory that Earhart and Noonan survived for some time as castaways on the island, subsisting on rainwater, small fish, and turtles. This hypothesis is supported by evidence from earlier expeditions, which uncovered a makeshift campsite and 1930s-era artifacts, including a jar resembling freckle cream believed to be cosmetic.

The disappearance of Earhart and Noonan prompted a major U.S. government search in 1937, which included aerial flyovers of Nikumaroro, then known as Gardner Island. The current expedition hopes that new technology and fresh examination of satellite data may finally solve the enduring mystery around Earhart’s fate. While opinions differ on the identity of the Taraia Object, the mission marks the latest chapter in ongoing efforts to shed light on one of aviation history’s greatest enigmas.
