Journal: In the event that you lose your SR-71 Blackbird Manual

In the event that the previous owner of your SR-71 Blackbird didn't provide an owner's manual and you need to review the ignition procedure, or wonder why the engines cut out when you idle the engine, Lockheed and the US Government have thoughtfully provided the folks at sr-71.org a copy which is posted online in entirety. Once in flight, if you are entertaining thoughts of pushing your SR-71 past Vne you should refer to pages 5-8 and 5-9.

It's an interesting read, and it still amazes me that this aircraft was designed between 1957 and 1962 and its performance envelope has seldom been matched.
