The video below by RollingThunder42, discusses the flight routes in the Southern “Hemisphere”. This was one issue that, when we discovered it, made us wonder what the heck was going on. Why would any airliner decide to fly into the Northern Hemisphere, while flying from a departure city in the Southern Hemisphere, to an arrival city also with the same hemisphere. That would make absolutely NO sense whatsoever on a globe earth.
However, when the flight routes are applied on the Azimuthal Equidistant projection (commonly known as the Flat Earth Map), things start to make a lot of sense.
