that is totally wrong. doesn’t fit the math.
and even if the points are close to directly opposite, the two routes on the map, route A and route B
are from the same departing airports while the two routes are far apart. Mathematically the distance between them is more than 2000 miles… They can’t have the same distance. and not the same time if you look at the time of each route.
But you need to prove it mathematically as I did previously.
