A SUB TO SEE

The Onyx, the only nonnuclear British submarine to have been used in the Falklands War, has been rescued by the Warship Preservation Trust, which plans to turn it into a tourist attraction.

The ship is nicknamed the "Sardine's Revenge" in accordance with a Salvador Dali fable in which a sardine watches a submarine pass and tells his children: "There goes our revenge, a great tin made of sheet iron in which men, covered in oil, are held inside, pressed against one another."
