New York (CNN) -- USS Cole Cmdr. Dennis Farrell keeps in his cabin a memento of the last time the storied Navy destroyer cruised into New York Harbor. It was Fleet Week 2000. Sailors stood at the rails under a fluttering American flag. In the background, the Twin Towers soared over a shimmering skyline.
