My Secret Santa had obviously done some spying on me as they got me the perfect gift. I'm a huge fan of the Lockheed SR-71 Blackbird spy plane and my SS got me a technical book about the design, operation and maintenance of the Habu. I've had my eye on the book for quite some time but hadn't bought it (I have a couple of other books about the plane). Now I don't have to buy it myself, Thank You very much Secret Santa!
