I recently read of an account by an American researcher in New Guinea who was looking for the wreckage of a US cargo aircraft that had disappeared during the war. He found, instead, the wreckage of a Mitsubushi A6M Zero fighter that had crashed in the jungle. The researcher found human remains and, as soon as he could, notified the Japanese government. There was enough left of the Zero do that the airframe and engine serial numbers could be read. Apparently the Japanese are as meticulous at record keeping as the germans because they had no trouble identifying the pilot and coming up with details concerning the Zero’s loss. If there were records involving Earhart and Noonan,, I’m sure thay would have turned up by now.
Not if they murdered the 2 of them IMO. But they do indeed keep good records.
