It's been written-off
Sunk in brackish water for days?!? No fixin' that - you'd have to replace, well, everything. It has indeed been officially Written-Off.
(Though it would have looked cool sitting in the old boneyard at MIA with the aging Connies, etc., back-in-the-day...gosh, I'm 'misting').
Great job Skully! Oh, and the most profound lesson he taught the general public, IMHO? - decisiveness in his decision making. Skill, experience, and Command Presence all rolled into one: "We'll be in the Hudson."
Bravo.
