One of the cooler things I’ve stumbled across on the Internet. This is an actual SR-71 flight manual, declassified and part of the public domain.
There’s a lot of interesting stuff in there (you might have seen checklists including the word EJECT before, but have you ever seen FL700 mentioned not as an operating ceiling?) and I’m sure a lot of the information will need to be unpacked by the more experienced members on the forum.
Have fun looking around at what’s included, and if you’re inspired by this be sure to vote for the corresponding feature request:
