I don't think this book quite deserves 4 stars, but 3.5 isn't an option, and I wanted in some way to show that I found it better than most of the books in the series. Not to say that the rest of the series is bad, but this one is a cut above. Unlike many series entries, which take a broad topic and try to tell too much in too few pages, this book took a narrower topic--the B-29 Superfortress--and discussed it in detail. Wheeler discusses its design, construction, deployment, its failures (and there were many, many of them, apparently), and ultimately its effective use. Also appreciated was a chapter looking at things from the Japanese viewpoint. The final chapter, however, which recounted the staggering destruction and provided some foreshadowing of what's to come at the war's end, I found to be heart-wrenching. It's a reminder of what a terrible thing war is, something that many of us all too easily seem to forget.
