Query: Dog-Fight

There is a great deal of interesting and valuable information in this book, but it is nearly ruined by extremely poor (or no?) editing. There are numerous, distracting typos as well as sentences that have obviously been rewritten but not had the original wording removed. Chapter subheadings are often followed by text that has little or nothing to do with the supposed subject of the section. Frequently, the author digresses into pages of information not related to the heading or even the title of the chapter! There are also very lengthy quotations from WWI flyer's diaries or action reports that, while interesting as memorabilia, tend to be redundant and add little to the narrative. Many of these sections could have been shortened to better effect. If you want a book about WWI in the air, find a used copy of Reynold's "They Fought for the Sky". You'll find it much more fun to read and less aggravating.
