I said Perth to Buenos Aires because the shortest path is almost directly across the south pole (allegedly). I am a Mariner and it is my profession that lead me to FE. I'm not the only one. Charts come in all sorts of projections (distortions) and most people never think beyond that. Furthermore GPS (which is really a more advanced version of loran, and not from satellites) and chart programs take most of the thinking away from modern mariners. Why do you think it was possible to navigate across oceans whether cultures thought the earth was flat or a globe?
