Following the bombing of Hiroshima on Aug. 6, 1945, which resulted in 140,000 deaths, the Makurazaki Typhoon hit the city one month later, killing 1,200. As noted in a previous column, the second bombing of Japan was scheduled Aug. 11 but was moved up two days due to expected bad weather, and the originally selected city of Kokura was changed to Nagasaki. On Aug. 9, 1945, a B-29 bomber, nicknamed Bockscar, after its commander, Frederick Bock, took off from the island of Tinian carrying a 9,000-pound plutonium bomb named Fat Man with a blast equivalent of 21 kilotons of TNT. Two weather observation planes scouted conditions over both target areas. At 11:02 a.m. on August 9, 1945, the nuclear inferno was unleashed 500 meters above the surface. Fastcast: Heat advisory.
