Rare Photo of the Mushroom Cloud Over Hiroshima Discovered in a Former Japanese Elementary School

Some interesting stuff at the link, along with the usual hand-wringing.

The person who took this photo would have been among the first to look out there and realize that this wasn’t just your run-of-the-mill bomb. It wasn’t the air raid that the citizens of Hiroshima had been anticipating for months. This was the beginning of a new world, one with a bomb unlike anything anyone had ever experienced before, something so new and fearsome that at first no one could understand what it was.
