Winding Tale Of Americans Coming Together To Capture The Earth. Why does every nonfiction book about the American side of WWII these days have to proclaim that whatever it is talking about "helped win WWII"???? Because let's face it - with many things, such a claim is tenuous at best, and perhaps the most glaring weakness of this text is that while the calcite is shown to be an important tool of the war, it is never truly established how it "helped win" the war. Indeed, the book as written does a far superior job of establishing how this calcite crystal that everything in the book revolves around was crucial in capturing "Earthrise", the famed Apollo-era shot of the Earth from orbit around the moon, than it does in establishing how this particular technology "helped win WWII".
Beyond the criticism of the subtitle though, this truly was a well documented examination of how a group of Americans that couldn't actively fight in the war - though some later did just that - still found a remarkable and obscure way to contribute to the overall war effort. Essential, during times of total war such as WWII. It also shows how these people - and the Polaroid Company - would advance knowledge of optics and sights to levels unknown before, and how such advances really did need such a wildly disparate group of people all around the country to work together to achieve a common goal.
Ultimately, this book is about teamwork and the "can-do" spirit that American propagandists of this and later eras were so ardently promoting - even into the modern era, in some circles - as much as it is the science and tech of the calcite and optics. So take that for what you will, though I will say that this book never actually feels like a propaganda piece. If anything, it feels so *real*, like you're actually there as these events are happening. That is clearly thanks to Hughes' research as well as the way he chose to write this narrative, and speaks well for his abilities in both arenas.
Overall an interesting book with perhaps a few quibbles here and there, but one esoteric enough that few (relatively, at least) will likely read it - even though it really does show a glimpse of an America and Americans rarely seen in reporting of this era. Very much recommended.
