This is one of those stories you see on the history channel when they are not doing a Hitler special. The Howard Hughes movie “Aviator” didn’t really touch at all on this part of his life. It is a compelling read about espionage at the deepest depths of the ocean. The retrieval of a Russian Nuclear sub. Enjoy the timewaster.
