Although Fat man that was dropped on Nagasaki was more powerful it led to 60,000-80,000 deaths as compared to 90,000-166,000 caused by little boy dropped on Hiroshima. The reason was Fat man missed its intended targeted location in Nagasaki by 3 km as a result of bad weather. The bombing was therefore confined to the narrow Urakami Valley and hillsides.

In charge of the mission, Captain Parsons thought that if something went wrong or the plane crashed during the take-off it would wipe off entire US base and kill thousands of soldiers with it. To avoid this it was decided that the bomb will be finally assembled on the flight. The air crew had to arm the bomb while it was hanging from a hook in the plane while flying over enemy territory.
