That's because it was the first—and only—nuclear-powered passenger ship to have ever been built. Science correspondent Geoff Brumfiel tells us about his recent tour of the ship and why it was a symbol of peace in it's time.

To see more pictures of Geoff's visit to the NS Savannah, including one from 1962 when the ship was operational, click this link.
