Still shaking my head over this one...
I am still trying to find an actual story on it. It was a report on our local TV here, my wife said it was also reported on TV earlier today, and I have seen a few mentions on forum --- BUT still no confirmation, and like you I find it hard to believe they can't find a Battleship.
I agree I saw the same TV program describing how the every one hunkers down there and even brings animals. I have to imagine if the USS ALabama disappered it would rivial the SuperDOme story this morning and we would be hearing all about it.
