This was my second read of this interesting little book.
Kennedy studies five problems that the Allies faced in World War II, from how to get convoys safely across the Atlantic, to winning command of the air, stopping a blitzkrieg, seizing and enemy-held shore, and defeating the "tyranny of distance". He explains the role that engineers played in solving each of the problems. It's a good story - as usual it suffers when I am simultaneously reading other more global accounts of the war which slice the issue differently. I think a reader who was not reading something else on the same subject at the same time would probably enjoy this more than I did. As it was, I was reading parts of the same story in at least two and at times three books at the same time, which I am learning is not conducive to an enjoyable experience with the book
