You seem to think that because the line on that pic is curved, that somehow disproves the fact that multiple other flights pass into the northern hemisphere before going back into the southern hemisphere to their destinations
I'm not sure what you think that 1 flight disproves smh
How many examples do you need for it to sink in?
It is impossible to take that flight path, in that short amount of time, and at the short a distance on a flat earth. Its commercially, physically and fiscally the dumbest flight path ever for any airline company to attempt to take.
