A group investigating the mystery of what happened to Amelia Earhart says it’s uncovered another similarity between the pioneering pilot and a body found 76 years ago on a remote Pacific island.

But The International Group for Historic Aircraft Discovery says its finding doesn’t prove the body is Earhart’s.

The group says a forensic analysis of a photo of Earhart shows a match between the size of her bones and those of the skeleton found in 1940 on Gardner Island in Kirbati. A 1998 analysis found a general similarity between the bones and a female of Earhart’s type.

Some critics insist the Pennsylvania-based group hasn’t found anything tied to Earhart.

Earhart’s plane vanished over the Pacific while she was attempting to fly around the world in 1937.
