Amelia Earhart's grave?

Someone has claimed to know the site of the grave of Amelia Earhart and her navigator, Fred Noonan. An American Marine, stationed on Tinian Island during WW II, had the spot pointed out to him in 1944 by a Hawaiian who claims to have helped bury a white man and woman dressed in aviator's suits in 1937, when Earhart went missing. The Marine claims to have tried to tell his story since then, but was taken seriously only within the last six months. He's been flown out to Tinian Island, and pointed out the exact spot. Archaeologists are to begin a dig sometime soon. Even the head of the archaeologist team thinks it's unlikely, but would be delighted if it turns out to be true.

I dunno: it's taken sixty years for the Marine to find someone to listen to his story? I'd have thought a phone call to either National Geographic or the History Channel would have sufficed.
