Expedition was drawn to Nikumaroro after spotting what was described as a metallic glint in waters off uninhabited island

A US expedition that voyaged to a remote Pacific island in the hope of solving the mystery of what happened to pioneering pilot Amelia Earhart has said an object they suspected to be her plane was a clump of washed-up trees.

“Unfortunately, we weren’t able to find that smoking gun,” said Steve Schultz of Purdue University, standing on the sand in front of a blue lagoon on the atoll of Nikumaroro, about halfway between Australia and Hawaii.

Images from New Zealand aerial survey of Nikumaroro in 1938 offer new clues over aviator’s disappearance

A New Zealand museum has released nearly 50 photos from a 1938 aerial survey of the island where Amelia Earhart is believed to have crash-landed, offering amateur sleuths new evidence to scour for traces of the pioneering aviator and her plane.

The black-and-white images were published by the Air Force Museum of New Zealand after renewed interest in one of the biggest mysteries of the 20th century, spurred by a US expedition to the Pacific atoll of Nikumaroro in search of new clues.

Researchers will head to remote Pacific atoll, but sceptics say satellite images unlikely to be of her aircraft

A team of US researchers is approaching a remote Pacific atoll where they suspect the famed aviator Amelia Earhart crash-landed in 1937, in the latest attempt to crack one of the biggest mysteries of the 20th century.

The 17-person expedition was inspired by satellite images taken over several years showing a submerged object in the uninhabited island’s sandy lagoon – evidence dismissed by other longtime Earhart sleuths who say it is probably a fallen tree.
