For those of us intrigued with seeing and understanding the interiors of places like aircraft gun positions, this book is both wonderful and disappointing. While there are some incredible modern photos and plenty of interesting archival information, illustrations and photos (the astonishingly complicated remote control gun system on the ME410, for example) I wanted the photographer to show me more. The book could easily have had twice the number of pages and gone into more detail on each aircraft. But as one reviewer has written, it's a coffee table book.
There are also a number of typos, even misplaced photo captions, but that seems to be a common problem in recent books. Have publishers cut out the copy editor position as a cost saving measure!?
Nevertheless, Gunner is a magnificent book that provides more information and photos and does so better than any other I've seen. It presents more than 20 aircraft from the US, Germany, UK, and Italy as well as an interesting section on the development of aerial gunnery in WWI.
Well worth adding to your collection, especially considering the reasonable price.
