There's also the flight back from Singapore. Now, a flight from Singapore to Newark New Jersey, the air port where I departed, across the Pacific would take an extremely long time, wasting the airline's fuel and probably requiring a few stop-overs. However, our flight path was to depart from Singapore, over Malaysia, over mainland China, over Siberia, over the rim of the North pole, over Alaska, over Canada and land in Newark. You see what we did here? We flew over the top of the earth because the earth spins beneath the plane, saving distance off the flight. I saw everything outside the window of the plane; I saw the Malaysian jungles, I saw the sparsity of civilization of central, mainland China, I saw the vast, frozen tundra of Siberia, I saw the North Pole, I saw more tundra in Alaska and northern Canada and so forth. If the earth truly looked as it did if you opened an Atlus, this type of flight path would add distance to the flight. You would have to go north, east, south, southeast and south again in a bizarre zigzag. However, since the earth is SPHERICAL, you can draw a straight line from Singapore to New Jersey through the North Pole.
