If you have seen the hole in the side of the McCain, my guess is that those missing were killed on impact and their bodies are trapped in the compartment that was opened to the sea and still flooded. Wont find them until there is a temporary patch is welded over the hole and the compartment dewatered. Or if the ship is drydocked, then they can dewater compartment. Either way, IMO that is where they will find the missing sailors
Ok, that makes sense. Thanks.
