I worked on KC-135's for four years, ('66-'70) and as far as I know at least up to 1970 the following proceedure was used. The tanker was on autopilot, to provide a stable platform; the refueling was an effort between the boom operator and the receiver pilot. The receiver was stick flown. This could result in some interesting stories. There was an automatic system that would perform auto- disconnect if various limits were exceeded, but it was based on cams, micro-switches, and an induction coil in the nozzle for communication with the receiver. All-in-all stone age. I don't know how the KC-10 works. I noticed on the tube the other day a report on an AWACs mission, and part of it was taped during IFR; the pilot was stick flying, I didn't see the tanker. So draw your own conclusions. As far as WW2 is concerned I have no idea why IFR wasen't used, but I would speculate that it wasen't needed; the cost of setting up a B-17 for IFR and building a tanker was too high. Only when the requirement for long range 12-24 hour missions was realized was it cost effective. BTW; I know of five tanker types; KB-50, KC-97, KC-135, KC-130, and the KC-10 in order of appearence. As I remember the first IFR was in 1923. Y'a can't go far without IFR. 8-)
