Its almost a good point, but it also happens above a plane(flat disc). A plane taking off from a point on a surface trace a circle and can come back to the exact point. Here's what more intersting in real life. Try to trace flight paths (true planes route on Earth) and try to see if you can find an INTERCONTINENTAL flight route tracing the equator. All of them climbs up first to the northern part before going back down to their destination.
