The book is largely centered on George McGovern's experiences in the war, as a B-24 pilot, and I would have liked to read more about the other pilots, co-pilots, and flight crew members. Ambrose mentions a plethora of other men, but merely skims most of them. The reader does not really get to know most of the characters, as they did in Band of Brothers (Ambrose's work concerning the 101st Airborne division, which I consider to be a better book).
I also wish Ambrose had gone into more detail overall. As some other reviewers have commented, the book does seem a bit rushed. Perhaps this stems from the fact that the concept for the book was not originally his - Ambrose picked up the project, on the recommendation of George McGovern, from another author who had already started it. Again to compare with Band of Brothers, I did not feel, when I finished this book, that I had as in-depth a knowledge about the AAF as I gained about the 101st Airborne. And while I have certainly gained respect for the B-24 bomber pilots and their crews, I did not come away with the overwhelming feeling of awe and admiration that I did for the paratroopers of E-Company in Band of Brothers.
I was also disappointed to see a lack of good editting. There are numerous typos throughout the text that should have been caught and corrected before publication. This bogs down the text in some places, as the reader takes a few moments to realize that "so" is supposed to be "do" and so on. The book is certainly not worthless - as I said I did learn from and enjoy it - but does leave something to be desired. It would probably be best recommended to casual World War II readers, like myself, and not to true scholars and history buffs, who I'm sure could find more useful references elsewhere.
