I did address your questions. Flat objects have edges.
As to your plane physics query? The gulfstream dictates wind speed. I've been on flights where we've arrived 30 minutes early because of a strong tail wind.
And your track query? It's the same distance in every lane. Lane 1 starts further back than lane 9 because it is further. Take a donut. Running a circle around the hole is much less than running a circle around the outer edge.
