All US Government records about Amelia Earhart are set to be made public - just weeks after a team of researchers made an unusual breakthrough in their efforts to find her.

The renowned American pioneer was seeking to become the first female pilot ever to circumnavigate the globe after setting off from Lea in New Guinea in 1937 with her navigator, Fred Noonan.

The US Navy's position has long been that Ms Earhart and Mr Noonan ditched at sea after their plane ran out of fuel.

But now, President Donald Trump has confirmed he will make the "Earhart files" public.

Her disappearance has "captivated millions", Mr Trump said on social media on Friday.

And he also teased that details of her "final trip" will be made available for the first time.

"I am ordering my administration to declassify and release all Government records related to Amelia Earhart, her final trip, and everything else about her," the President added.

Kimberlyn King-Hinds, the US Commonwealth of Northern Mariana Islands' delegate to the House of Representatives, had requested the files be declassified in July.

Ms King-Hinds revealed that numerous elderly residents had shared "credible, firsthand accounts of having seen her on the island of Saipan".

Some have long believed she may have landed on a small island in the Pacific or been captured by Japanese forces.

And in 2017, an archive photograph was found of Jaluit Atoll in the South Seas Mandate, the interwar Japanese administration over the Marshall Islands.

The photo includes two European-looking people - sparking forensic analysts to claim it was "very likely" to be a picture of a captured Ms Earhart and Mr Noonan.

A ship in the background of the picture flying a Japanese flag is theorised to be the Koshu Maru, a Japanese naval vessel which would have been involved in transporting captives.

The Koshu Maru is said to have transported the pair to Saipan, where they allegedly died in Japanese custody.

Ms King-Hinds continued: "In pursuing clarity for my constituents, I have become aware that the US Government may still hold documents or records related to Earhart's journey and final whereabouts that have not yet been made public.

"Should such records exist, their release would contribute meaningfully to our understanding of one of America's most revered aviators and could finally shed light on the final chapter of her remarkable life."

The President's intervention comes just weeks after scientists at research firm Nauticos restored an 88-year-old radio in a bid to track down Ms Earhart's last known location.

Researchers restored a Western Electric 13C aircraft transmitter and a Bendix Model RA-1A receiver.

As a result, they said they were able to exactly pinpoint the American aviator's exact location at 8am on the day it disappeared.

Until now, researchers had been surveying around 3,610 square miles to track down the plane's wreckage.

Nauticos will now be launching a fourth expedition, carrying out tests on the exact radio used by Ms Earhart to recreate the circumstances leading up to her disappearance.

The expedition's project manager, Jeff Morris, said: "The fourth Nauticos mission to search for Amelia Earhart will be based on the scientific data that we've collected during extensive radio testing.

"This is no longer theory.

"This is scientifically-measured information that tells us where she was at 8am on July 2, 1937."
