On 9 August 1945, three days after the bombing at Hiroshima, the United States dropped a bigger atomic bomb on Nagasaki. The nuclear bomb called "Fat Man" was dropped by another American B-29 bomber, Bock's Car.
Kokura Arsenal was the original target, but due to smoke and cloud, the bomb was dropped on Nagasaki. "Fat Man" was dropped at around 11.02 am local time, which exploded 1,650 feet above the city on 9 August.
The attack destroyed a third of the city and killed more than 40, 000 people instantly.
"It seemed as though the sun had burst and I was lost in its midst. I threw myself at once into a clump of young bamboo trees. I was lying on a big bag of grass. My face only felt hot," Globe and Mail quoted a survivor as saying.
