Nagasaki remembers 08/09/45. "Nagasaki was not intended as the original target for the atomic bomb. The US bomber had been heading to Kokura, but the city was covered with thick cloud on the day. The plane circled three times before changing course for Nagasaki.
When it arrived, Nagasaki too was covered in cloud. With dwindling fuel supplies, the pilot was about to turn back when a break in the cloud appeared."
