4 stars for the historical content, but 3 stars for the writing, and I always round down when rating. I feel like this book was trying to be both a focused "looking at a big event through the lens of specific person(s)" book and a general scholarly overview of WW2 in general, and as a result, both approaches kind of faltered. There isn't enough depth of detail to fill the latter, and not enough connection to fill the former. I wish this had been marketed as a short history/examination of modern aircraft in American warfare, rather than making it sound like an "Unbroken" type story about specific soldiers. I think it would've been a more successful book that way.
