At 11:02 a.m., a nuclear weapon was dropped on Nagasaki by an American B-29 bomber directly killing 35,000 people, 6,200 out of the 7,500 employees of the Mitsubishi Munitions plant, and 24,000 other workers and 2,000 Korean slave laborers.

By the end of the year, injury and radiation brought the total number of deaths to 39,000 – 80,000 of the population of around 263,000.

Fat Man was the codename for the atomic bomb dropped on the Japanese city of Hiroshima.

Fat Man was dropped and, following a 43-second duration free fall, it exploded at 11:02 local time, at an altitude of about 500m.

Although Fat Man was more powerful than Little Boy used on Hiroshima on august 6th, the effect was confined by hillsides to the narrow Urakami Valley.

Named Bockscar, the USAF Boeing B-29 Superfortress bomber became the second – and last aircraft to drop an atomic bomb.

Bockscar is on permanent display at the National Museum of the United States Air Force in Dayton, Ohio, next to a replica of a Fat Man.
