Interesting. Hard to imagine the debris getting out into the main channel though, think it would just fall right next to the hulk. And nothing navigates near the Arizona other than tour boats. The big carriers do dock on the other side of the channel there, so I could see some concern.
btw, the Missouri had just come out of dry dock with a new paint job and looked like a brand new battleship. The paint looked to be about 1/4 inch thick and other than the small dent on the edge of the main deck where a kamikaze had hit and bounced off, she looked perfect.
Got video (illegal, but everyone was doing it) of the Missouri getting towed out after the redo, past Bldg 38 where I worked. So damn close I could not go wide enough angle to get the whole ship, so I panned back and forth. Beautiful ship, classic lines. Did a tour several months earlier, and the rust was very apparent, needed the facelift bad.
The rails were lined with sailors that had reenlisted on her as a special ceremony before leaving the drydock.
