I will go only so far as to say that I knew what an atom was.

A bright light filled the plane. The first shock-wave hit us. We were eleven and a half miles slant range from the atomic explosion but the whole airplane cracked and crinkled from the blast... We turned back to look at Hiroshima. The city was hidden by that awful cloud... mushrooming, terrible and incredibly tall.

I'm proud that I was able to start with nothing, plan it and have it work as perfectly as it did... I sleep clearly every night.
