This "Survival Town" house, some 7,500 feet (2,286 meters) from a 29-kiloton nuclear detonation, remained essentially intact. Survival Town consisted of houses, office buildings, fallout shelters, power systems, communications equipment, a radio broadcasting station, and trailer homes. The town was built for a Civil Defense exercise and to test the effects of a nuclear blast. The test, called Apple II, was fired on May 5, 1955.
