You don’t know Jack, do you? Do you want to get to know him? Do you want to tell him what you think about his blog? Do you want him to answer questions you have about the Navy?
If the answer to any of these questions is yes, then you are
out of luck in luck. Jack neither reads or answers emails. He is far too busy. But if you still want to try, you can use this contact page to write to him. All messages go directly to his email account spam box and are promptly deleted. On the other hand it never hurts to try. Enter required information, ask your question and Jack will post an answer to your question sometime before the Earth crashes back into the sun. Give it a whirl.
