It’s one of the biggest mysteries in history, but now Amelia Earhart’s plane may have finally been found.

Researchers from Project Blue Angel are investigating a mysterious wreck off the coast of Papua New Guinea, which they believe could be the famous pilot’s lost plane.

William Snavely, director of the project, said: “We're still exploring to try to find out whose plane it is. We don't want to jump ahead and assume that it's Amelia’s.

“But everything that we're seeing so far would tend to make us think it could be.”

Divers first explored the wreckage in August, where they discovered several characteristics of Earhart's plane, as well as a glass disc, which could be a light lens from the plane.

Speaking to Live Science , Mr Snavely said: “It's obviously glass that appears to be old and covered significantly with barnacles.

“It has a rough shape and diameter that appears to be relatively consistent with lights that were on the plane back in the 1930s for Lockheed.

“But we don't know for sure if it's a Lockheed light. That's what we're getting checked right now."

The team is now crowdfunding on GoFundMe in the hopes of raising enough money for  a second dive.

Earhart disappeared in 1937 during an attempt to make a circumnavigational flight of the globe alongside navigator Fred Noonan.

There are several theories about what happened to her.

Some believe that Earhart and Noonan were captured by the Japanese, while other suggest that the pair became castaways on a distant island.
