A great source for first-person accounts, but vaguely unsatisfying as far as historical color and texture are concerned. Does not probe deeply into the moral or ethical questions raised by Hanford's planning and purpose. Makes few mentions of the environmental damage until the afterward -- though part of this may be the lack of documents that have only recently been declassified. Also, hearing people who literally in some cases put their hands on the bomb that would kill hundreds of thousands of Japanese civilians claim that dropping the bomb saved countless lives started to feel like doublespeak after the fourteenth repetition. Especially since that particular line has been somewhat debunked.
