He gave his explanation:
The globe model is wrong and when we compensate for the flatness of the maps, we get the proper, flat earth map.
This falls apart if you actually try to use the maps over long distances.
That's right because if you are say, planning a journey accross the Pacific, you need to know the total distance to cross it before you leave port, so that you can carry enough fuel and supplies. There are nautical maps of entire oceans that have a global projection over them. You can then use those projection lines to work out what the distance is in any direction. The Pacific is a good example because it covers almost half the globe. There's no way a flat map would ever work as a tool to navigate it, without the global projection.
At the end of the day you can't argue with actual distance. No flat map can ever get the distances between continents right, the perspective will always be wrong. Gnomonic projection on the other hand allows mariners to use 2D maps to accurately plan routes, work out distances. The important thing is that the maths of a globe are accurate. If I read a Gnomonic projection it tells me Cape Town to Southern Argentina is approx 3800 miles. I work out I can do it in 12 days. I take fuel and supplies for that. And guess what, it really does take 12 days and is 3800 miles. I don't understand why any FEer can't get their head around that. You can't doctor the distances that thousands of vessels sail every day. They are what they are, and they say globe.
