Hi,
maybe a barmy idea,
what about nav plotting for some of the bombers (the ones that had navigators) somthing along the lines of the cvs. you plot your course in map room, you take off and auto pilot follows route, but here's the neat bit, the autopilot only roughly follows route, what you have is some way of fixing position by using landmarks on ground (airfields, hills, rivers, coast lines).
any comments:
