78 years ago.
The second of the Atomic bombs used in anger, it was, essentially, the Trinity device all over again, only this time mot an experiment, but used in anger.
It’s use effectively ended the Japanese war making energy. No all wanted to surrender, but enough did want it that it happened….and thus the war ended.
The city (and people) of Kokura was lucky that day….Smoke and weather precluded a good bombing run, so the target was moved to the secondary choice…..Nagasaki.
Luck plays an important part of survival sometimes.
Most of the time
