[The USS Cairo, first of the US Navy's City class ironclads, was designed by Samuel M. Pook and built by James B. Eads, representing a sea change - get it? - in marine warfare technology. After sinking in 1862 it remained undiscovered on the riverbed until 1959; more than a century's rest was disturbed when the ship was raised on this day in 1964. Currently preserved at Vicksburg National Military Park, it serves its country once more as a museum and tourist attraction.]
