Amelia Earhart contoversy

I was thinking about a documentary I watched along time ago, and I think you guys should hear about it. It was about the disappearance of Amelia Earhart and her navigator somewhere of the Pacific. The documentary's main point was that this was near the start of WWII, and that it is possible that their plane crashed or ran out of fuel, and that they were picked up by the Japanese on occupied islands. I don't remember the navigator's name, but apparently he had a plane design that was very effective and fast (may have won an air race). This plane showed a very similar likeness to the Japanese Zero fighter, almost too much. The rumour is that he gave the design to the Japanese. i can't remember what else the show said, they may have been living in hiding or something. Please don't think anything here is true, it is just a theory i remember seeing on a tv show a year ago
