This new book on the SR-71 provides a excellent compliment to Schiffer Military's "Lockheed SR-71 Blackbird: The Illustrated History of America's Legendary Mach 3 Spy Plane" by James Goodall, which is a much larger, more expensive book; this also serves as a replacement for the strong-selling book on the aircraft by Bill Holder, which was released in 2002 and is now out of print.
