Second on Skunk Works by Ben Rich. Absolutely a great read and lets you in on some things I've never heard before that went on during the cold war.
Also Baa Baa Black Sheep by Pappy Boyington. I actually have an autographed copy. Great book, a cool look into the Flying Tigers as well as the black sheep, and his life. They just don't make guys like that anymore, and that's a damn shame!
