Hostile skies; a combat history of the American Air Service in World War I

Hudson took great pains to insure the accuraccy of this book, and continued to seek out information about the men and units he wrote about in this book. It is THE BOOK on the fledgling American Air Service, and having been a WWII fighter pilot, Hudson wrote from a pilot's point of view, and was able to discuss the salient points and the bad points of the experiences that these men had and how it shaped the future of our air force. I strongly recommend it to any serious military student. --reader review, amazon.com.
