The book Spy Sub...sucks! It is exactly what the write up I found on it after I bought it says! It is about a guy on Halibut (aka: Viperfish) during the mission...he knows nothing and finds out nothing. Silent Service indeed!
But...there was a chapter in the book...rolling on the waves and puking that was downright hysterical. Someone winds up puking and everyone calls back after every hurl "Ralph O'Rourke isn't down there, sir!"
I guess you guys really need a sense of humor to serve.
