On November 11, the SS United States, a former record-breaking ocean liner, was deliberately sunk in the Gulf of Mexico off Florida's coast as part of a $13.5 million project to create an artificial reef. The process took several hours longer than anticipated; crews filled 128 tanks with water to ensure even sinking, and by 9 pm, the ship had tilted and fully submerged.
