The ninth of August 1945 was a cloudy day in Nagasaki, as it was on other parts of Kyushu as well. But just around eleven there was an opening in the clouds, which was very unfortunate, because above the clouds there was a US airplane with a lethal load and the opening in the clouds made it possible to drop that load on Urakami, the nothern parts of Nagaski.

This clock is among the first thing you see when you enter the Atomic Bomb museum.
