Beautiful proof planes fly over a flat earth and cannot fly over a globe.
...An examination of this data eliminates a potential objection by GE folks that plane is flying with the curvature of the earth since the plane cannot be tracking with the curvature and ascending at the same time. By it’s very definition, the plane is moving away from the ground (ascending), not tracking with it as it should during cruising altitude. This might seem obvious to most logically minded folks but we are dealing with hardened attitudes that will use any argument, no matter how illogical, to avoid the conclusions reached here.
Since the plane is ascending, and if we are living on a ball, we must take into account the ascending and curvature rates at the same time. There is no getting away from this. This also destroys the idea that gravity keeps the plane moving along the curve, since if this was the case, a plane could never ascend at all. The ascent angle over time is the key.
