Stupid. That, of course, is because the light is bent slightly while travelling close to the sea surface. And photos from great height showing curvature? It's only the lenses that distort the picture, as every one knows who's ever used a wide-angle lens.
Netflix had a doc about the flat earthers. One group got funds to buy a fairly decent lasers, so set out to find.. err.. a flat bit of ground. Laser at set height, target some distance away, and thus dot from laser should appear at the same height. Ergo, Earth is flat!
Program ended with the motley crew trying to figure out why it was higher on the target, in line with the conspiracy theory involving a non-flat Earth.
Shame someone had to die to try and prove their theory, but the 'accident' was probably sabotage, and if he'd achieved his goal, would have crashed into the hard ceiling above the flat Earth anyway. All the world's a (sound) stage.
