↑Museum of Technology Placard: "This flag was recovered from the wreck of the U.S.S. Ebon Atoll, a U.S. Navy Missile Cruiser, sunk off the coast of Alaska in 2066 with all hands lost. The cutting edge vessel's loss was due to a nuclear torpedo strike from the U.S. Navy Submarine, the U.S.S. Interference during the Anchorage Campaign. The submarine mistook the cruiser for an enemy vessel during radio silence and sunk it before obtaining vessel confirmation. This ranks as one of the most tragic disasters in U.S. Naval History since World War II."
