I'm leading more towards JFK Jr, is dead, and the plane he took was rigged to land in the ocean by someone in the government to make him disappear. They did say in the Doc he used a new plane, that went faster. It could have been rigged with auto pilot or something. But I also think enough people fake their deaths that it could be a logical path for him also. But I do lean towards he is dead, but his death will be exposed as murder.
