I still dont understand... The curve is already counted in on a flat projection of the earth.. thats why continents and states are distorted. So wouldnt that mean that the shortest path on a flat projection of the earth would be a straight line...

The term he used was antipodal points. 'In mathematics, antipodal points of a sphere are those diametrically opposite to each other (the specific qualities of such a definition are that a line drawn from the one to the other passes through the center of the sphere so forms a true diameter).[1] This term applies to opposite points on a circle or any n-sphere.'

All flight planning software uses an ellipsoid (like WGS 84) and a hundred thousand flights per day arrive at their destination. So I'd say that the predictions of spherical/ellipsoidal geometry as it relates to the Earth have been verified literally millions of times.

If you are actually suggesting planes navigate using spherical geometry and the Great Circle, that flies in the face of reality. Planes use the polar coordinate system, which is cartesian in nature, just with zero at the center point directly under Polaris. Earth is not a planet, to begin with, and certainly all patents for aircraft are based on a fixed plane, i.e. flat earth. So you are lying to yourself and living a total fantasy if you think aircraft follow a curved path of any sort. The path is curved because the maps are curved. Look at the flight path on an Azimuthal Equidistant map and you will see its a strait line over a level plane.

Mindless flattard garbage. The distance from Johannesburg to Sydney is 12000km. Direct flights between the two cities are conducted weekly. On a moronic flat earth the straight line distance is more than 23000km. There is no commercial aircraft capable of revenue flight across that distance. You flattards suck at basic geometry.

@@TruckerCarlson- congratulations, you are 100% incorrect. In a three dimensional Polar coordinate system, points are defined by a distance from the origin and two angles from two reference planes (usually orthogonal) which is completely different from a Cartesian coordinate system where points are defined by three distances from the origin along three (usually orthogonal) reference planes.
