A team of researchers is currently bobbing across the Pacific Ocean toward Nikumaroro Island, driven by the twin engines of scientific curiosity and what can only be described as an admirable commitment to a very specific hunch. The group, from the US-based Archaeological Legacy Institute (ALI) and Purdue University, expects to arrive by Monday to inspect what they believe could be the wreckage of Amelia Earhart's plane.

Earhart, the American aviation pioneer, vanished in 1937 while attempting to circumnavigate the globe, a disappearance that has since generated enough theories to fill several very thick books, a few documentaries, and at least one ongoing family argument.

The team is hunting for what has been dubbed the Taraia Object, first spotted in satellite imagery in 2020 sitting on the edge of a lagoon off Nikumaroro. Purdue University notes that the object has since been confirmed to appear in aerial photography dating back to 1938, which is either a promising lead or a testament to the enduring visibility of trees.

The researchers are roughly halfway through their journey aboard the Marin Mainiku, a Kiribati National Shipping Line vessel. They departed the capital of Kiribati on Wednesday for the 830-mile trip to Nikumaroro, which is also part of the multi-island nation. Upon arrival, they will have to navigate a narrow gap in the atoll's reef created by the British in 1963 - the last time anyone actually lived there, presumably before they got bored and left.

"Finding Amelia Earhart's Electra aircraft would be the discovery of a lifetime," said Richard Pettigrew, head of the ALI and the expedition lead, demonstrating a level of optimism that has thus far survived multiple previous failed expeditions.

Earhart had already successfully flown from California across South America, Africa and Asia in her Electra twin-engine plane when she arrived in Lae, Papua New Guinea on 2 July 1937. From there, she and navigator Fred Noonan planned to head toward Hawaii and then back to California. Instead, her plane vanished without a trace while trying to reach Howland Island, a remote, uninhabited coral island near Nikumaroro, to refuel.

The official explanation remains that communication problems prevented the pair from finding the island, and Earhart crashed into the ocean after running out of fuel. This version is largely accepted, though no physical evidence has ever been recovered - which has not stopped anyone from theorizing.

One popular theory holds that Earhart unintentionally navigated to Nikumaroro, ditched her plane, and died a castaway. Images of the Taraia Object show what could be the remnants of a small aircraft in shallow waters, or possibly just a tree, depending on who you ask.

Ric Gillespie, who specializes in recovering historic aircraft wrecks, told Reuters that the object looked like a tree that had fallen from the atoll into the nearby water. "I'd love to find that airplane. It ain't gonna happen," he said, in the tone of a man who has been asked about this before.

The researchers credit Gillespie with previously finding evidence of human presence on the atoll in the 1930s and forensic analysis of skeletal remains found there in the 1940s, which they say lends credence to their theory. Gillespie, for his part, suspects Earhart's plane broke apart and its fragments were carried into the depths of the Pacific long ago, which is a less romantic but probably more accurate assessment.

Previous attempts to find the Electra have also come up empty. In 2024, researchers thought sonar imaging might have located it around 4,877m (16,000ft) below the surface near Howland Island, but that turned out to be a rock formation. In 2019, an expedition led by the marine archaeologist who discovered the Titanic investigated a photograph of what might have been a landing gear protruding from the water near Nikumaroro. It found nothing.

Undeterred, the current team sails on, proving that when it comes to Amelia Earhart, hope springs eternal - and so do the shipping schedules of Kiribati.
