Once when I was offshore on a drill ship, I remember being utterly fascinated when I read about the story of a CIA ship pretending to search for "manganese nodules" but was in actual fact searching for sunken Russian submarines. I almost blew my gasket when I realized the ship in question was the same one I was sitting on at the time.
