People have been looking for any remains or clues about Earhart for a long time. I was in the Western Pacific (island of Saipan) in the early sixties and we had a number of visitors on expedition to search for clues. They interviewed natives and people with roots back to that timeframe. We never heard of anything substantial being found. There was always the rumor of her flight going down while on secret mission to spy in Japanese locations in the Pacific...but, who knows. They continue to look.
That sounds like the visit of Fred Groener researching his book “The Search for Amelia Earhart.”
There is also Michael Campbell’s “Amelia Earhart: the truth at last.”
