Amelia Earhart was imprisoned by the Japanese and died in Saipan
Here is a zoomed in portion of the famous photo of Amelia Earhart and her navigator Fred Noonan taken in July 1937 after her official “disappearance”. In the full picture you can see a ship towing her plane Electra. Had her name been listed in the caption/description of the photo, it would likely have been classified and/or destroyed by the CIA together with all other photos of her taken after her disappearance. This particular photo survived because it was accidentally misfiled.
The fact that Amelia Earhart was imprisoned by the Japanese and taken to Saipan is regarded as an indisputable fact due to the many eye witnesses involved, but there are of course many things we do not know about her whereabouts and mission the summer of 1937. One line of thinking (backed up by evidence even though it cannot be proven) is that the Earhart story had to be covered up to hide the fact that president Franklin D. Roosevelt was indirectly responsible for her death (the two met prior to her last trip), and that he had prior knowledge about the Japanese military codes which were in use also during the upcoming war. With access to the codes, FDR had prior knowledge of the attack on Pearl Harbor 1942 which you can read about for instance here. The story suggests that FDR had convinced Earhart to carry a spy camera on her plane and she was taking pictures of the Japanese navy before being shot down by the Japanese.
Below are a couple of youtube films about the cover-up and possible scenarios, but even liberal History channel has made a documentary admitting a cover-up even though they do not credit those who made the initial research. Do check also Mike Campbell’s website to see more research.
