Query: This is a great book

I really liked this book. The pictures are great and there is alot of good history on the development of the airplanes. Plus the diagrams and the list of units using the aircraft add some extra pop that you do not normally see in other books. Some good companion books for related planes are The Skunk Works by Ben Rich and Lockheed Stealth by Bill Sweetman.
