  Wait, i don't understand. I was under the assumption that this text was a joke, but now I'm seeing it in reference to air force training materials? Is it a joke there as well or did someone actually write this text seriously, and plan for it's use as intelligible instruction?

    There's oodles of references to this online but nothing really I've found so far explaining whether it was ever intended to be taken seriously in the first place. It's hard to imagine anyone doing so.

      It's apparently from the 50s, as seen here: https://archive.org/details/sim_electronics-now_1959-03_30_3/mode/1up https://archive.org/details/sim_electronics-now_1959-03_30_3...

    Yes, it's a joke. It's not complete nonsense, though, unlike the Turboencabulator. There's a real explanation buried inside there. ("Where it isn't" is the target position, so it's looking at the deviation between where it currently is, and where it should be. The next time step, "where it wasn't" is the old target position, and so forth.)

  That's the voice. :-D
