If an aircraft flies with it's belly facing the earth (or "Blue side up"), the how can it fly around the world without flying inverted?

  • $\begingroup$ @thales727 This is much better suited to a physics site. A frame of reference is a relative coordinate system. Just like "up" is the same in antartica as it is in the north pole, the difference is your frame of reference. In the image above, the FoR is something in space, like the moon. If you were in the aircraft, the FoR would be your place in the plane. By the way, FL430 is not considered "extreme low earth orbit" just like 8 inches off the ground isn't "ultimate low earth orbit". $\endgroup$
