If you're at all interested in the history and development of these kinds of aircraft and the process that went into them, I cannot recommend enough the book "Skunk Works: A Personal Memoir of My Years of Lockheed", by Ben Rich who was the second director. It covers the era of the U-2, SR-71, and the F-117 Nighthawk including the initial earliest development of stealth. Fascinating inside baseball about the politics of such things in the Cold War too, the various issues with different services. They did amazing work, and they did it on time and on budget, even as bureaucracy slowly got pushed in more.
