The SS United States and her final destination

She was the fastest ocean liner in history, widely known as America’s flagship, and in her nearly two decades in service, the elegant SS United States carried four presidents, countless celebrities, and tens of thousands of happy voyagers.

Now, the SS United States is scheduled to sink off the coast of Florida, to become the world’s largest artificial reef. Correspondent Lee Cowan looks back on the history and future of a maritime legend.
