    40 minute video is a pretty big commitment, but it's super cool hearing
    from an actual engineer describe how this complex engine works.
    "Convergent Divergent nozzle" is an intriguing technology, and the
    temperatures he rattles off effortlessly are breathtaking when you
    think about what it actually means.

    Someone did their homework:-) Along with hours/hours of testing the
    engine design.

    For the pilot, I suspect it was more about monitoring the gauges than
    piloting the SR-71 Blackbird. Each mission was pre-programmed into
    the navigation equipment, so the autopilot was engaged.
