Query: An excellent survey!

This is a surprisingly good book about a subject that has been already covered in tons of ink. Kennett has written widely on air warfare, and held a visiting professor position at the National Air and Space Museum. Many other works have examined combat or industrial aspects of the war, but his is still the best overall survey: balanced, very well thought out, well-argued, and not so drenched in detail as to confuse the reader with a welter or jumble of data. I strongly recommend this for the bookshelf of anyone interested in the use of aviation and airpower in the Great War!
