Lockheed SR-71 take off protocol
If you are referencing the manuals found here the procedures look pretty standard to me. Granted they involve some thing specific to the plane they are generally what one would find. Pages 2-19 through 2-23 seems to cover the start up procedure and it looks pretty standard. Make sure ground unit is connected, check fuel flow, check engine is open, start, check RMP (provides some trouble shooting for RPM issues as well). It also goes on to say left engine first for odd flights and right engine first for even flights to keep the wear some what in line. There are a lot of "Note" sections but you are talking about one of if not the highest performance aircraft ever made so these are to be expected.
