Amelia Earhart can’t seem to rest in peace. People have been on the hunt for what happened to her ever since her plane vanished over the Pacific Ocean in 1937 as she attempted to become the first female pilot to fly around the world.

Every few years another new theory raises hopes without solving the mystery. Now, investigators believe they have discovered something that would support a decades-old theory that Earhart and her navigator, Fred Noonan, were captured by the Japanese: a newly unearthed photograph from the National Archives that purportedly shows Earhart and Noonan — and their plane — on an atoll in the Marshall Islands.
