Many, many years ago I took a last walk through a USN ship I had sailed on for a couple of years. The next day she was going to be decommissioned. It felt like a tomb as I walked through it. It was almost as if it had died and it's soul had departed.
I can imagine sleeping on the JFK in winter under tow with all the ghosts wondering about.
I would like to recommend to all CV lovers the greatest novel about the life and near-death of a carrier. Check out “Hero Ship” by Hank Searls. He was on a different ship at Okinawa and witnessed the fight to save USS Franklin. A lot of that went into the climax of the novel.
