But dont forget your never lost until the circle of uncertainity is larger than the map you are carrying.
Oh my. I had some room in my flightbag and used to carry the Pilots' Free Flight Atlas (East), covering Europe, SE Asia and Middle East with me. (A bit overambitious perhaps, I know.) Are you saying that with that on board I should never go lost again? Temporarily unsure of position, yes, but never lost? I might want to make room for that in my flightbag again, then.
I've heard another one that I liked, supposedly uttered by an SR-71 Blackbird pilot once: "You've never been lost until you've been lost at Mach 3"
