Bump
Wife and I took this Navy boat out to the Arizona Memorial a few years ago. When we got within 100 feet of the wreck, I caught a whiff of the N6 fuel oil that continues to bubble up. The Arizona went down with full bunkers, we were told.
Another issue is the age of the BB, now underwater for going on 75 years. There is concern that she could collapse, turning out the million plus gallons of oil and the remains of those who were lost in the attack.
The Navy has considered building a cement sarcophagus around the Arizona but the memorial is a very tender subject and no commander wants to take up this challenge.
