Its not really relevant, but this discussion reminded me of an amusing experience many, many years ago when I was FO on a DC-10 flying overnight from Miami to London. The INS on that aircraft could only hold ten waypoints which, with Freeport the first, took us into the middle of the Atlantic. Lets say that, by the time we got to waypoint 9, the two of us up front were not quite as awake as we should have been and the aircraft started turning to the next waypoint, number 1, which was still Freeport. Luckily the Flight Engineer was watching, in fact with some amusement, and, after we had started the turn, tapped me on the shoulder and suggested I might like to do something about it, preferably without waking the Captain.
Unfortunately, I never did get to buy that man the beer I promised him.
