Pretty cool and historical that the USAF specified that its 1956 fighters should be capable of remote control via the Sperry Zero Reader directing the autopilot, right? Hopelessly precious, to be sure, but even that is grist for the historian's mill. Anyway. What's a Zero Reader?
Stop giving me those pitying looks. I figured it out. The Sperry Zero Reader is just a flight director. I feel dumb not figuring it out, or at least not pursuing the question far enough to find someone to explain it lucidly.There's a little more to be said about its gyroscopic magic, and it wouldn't be Fifties-era militariana if it weren't a little sinister in a nuclear-holocaust-sort-of-way. I'm also going to touch base with a classic of history of technology, Donald MacKenzie's Inventing Accuracy. Looking back a generation later, it does seem to me that MacKenzie's pioneering work ought to have been the starting point of a historiography rather than all the profession has written on the subject. There's a lot going on here that historians could pull into perspective so that we could understand this world of ours before we run head on into slow motion disasters like the 737Max grounding.
