here is an argument i havent heard yet.
this is the scale of Australia, in “true scale”
which is roughly the length from france to north america.
however, on the flat earth map, its a difference
So according to this logic, it should take twice as long to fly from one side of Australia to the other, as it does to get from france to north america.
If he does some “airlines are inn on it, and fly slower” bs, then scale it down, and say north in canada, and south in australia, and measure how far you would get on the map if you drove for an hour. Because the flat earth map is so out of proportion that it cant make sense.
