The Zero G Plane is maintaining the same altitude over the ocean with exact horizontal flight. We do not have to dip the nose or descend to keep from gaining altitude over the Earth.
Prove it.
So far all we have along these lines is the same repeated baseless assertion.
The amount a plane would have to dip to follow the curve is so tiny it would not be felt.
As for your latest meme, again it is pure nonsense.
You have brought up that exact same argument before and had it refuted.
Oceans are level, but not flat.
You are aware the sun doesn't just shoot out light from the centre?
You also seem to completely ignore how a reflection works.
It doesn't just hit the surface then cruise along.
And for a FE, your sun is far too low. You have it at head height.
For a FE, you should see the sun vanish high in the sky, or always see it.
With the claimed 5000 km above the surface, in order to have it within a degree of the horizon (ignoring refraction which would make it appear higher) you would need to have it over a point roughly 290 000 km away, i.e. well beyond the range of the known Earth.
As such, it would never appear to set for a FE.
So that picture is nothing like what you would expect for a FE.
And of course you massive exaggerate the curve.
For a curve like that you would need a much greater altitude. Like from a mountain, which has already been brought up before in favour of a RE, where the sun initially shines upwards, casting shadows upwards, and illuminating the tops of objects before the base.
Try redrawing the same meme, but this time make sure for the FE you have the sun at the appropriate height, showing how it is no where near the horizon.
For the RE, draw in the expected curve, not a massive exaggeration.
And for both, draw in the reflections properly, from all of the sun, not just the middle.
