Experiment: Find non-stop flights between cities in the Northern Hemisphere that go primarily West-East until you circle the entire earth. Now do the same for non-stop flights in the Southern Hemisphere. You will find that the flight times are basically the same. This means that distance traveled is roughly the same since the airplanes used all have similar cruising and maximum speeds. Please explain how the earth can be flat and yet it takes the same amount of time to travel the Northern Hemisphere as the Southern Hemisphere.
