The U.S.S. Kailua has been discovered off the coast of Hawaii in 2,000 feet of water. The intact "ghost ship," which sank in 1946 after being used as torpedo practice, is still upright, with its solitary mast still standing and the ship's wheel still in place. From 1923 to the time it sunk, the ship laid countless miles of submarine cable in the Pacific.
