I remember being reported that SR-71 missile evasion procedure was simply to "accelerate and outpace". But I cannot find it in the manual :( !

I just finished "Skunk Works" by Ben Rich. I believe he said something similar in there, but I would have to find the exact quote.

The maintenance manual is a fun read too. A lot of the repair procedures end with PTF.

That means “Pound to Fit” (with a hammer or mallet). The panels flexed so much that they would come back a different shape than they were manufactured and had to be hammered into place.

This is a remarkably slow website for such a fast plane.

If you enjoy such gems, check out the procedures for C130 transport aircraft. An old colleague used to be a load master on them (before going into tech), and said the action required for a situation where your load is jammed on exit and you can’t cut the chutes deployed to extract the load from the cargo hold is “prepare for crash landing”.

I do enjoy the bluntness of military checklists.
