Why the fuck do need to defend a smartphone app I didn't create? Also ships over the curve? No, you're a fucking shill or just a retard with a double digit IQ. I see a rusty ship that's covered by narrow band mirage and looks like it's scuttled in shallow water.
You keep linking the same video over and over hoping for a different result each time, go curl up inside an oven.
If it was just a mirage and diminishing lines/perception. Then why can you go higher up altitude and see more into the distance? Go up a mountain you can see much further, on the ground not as far. Simple, the earth curves, and the higher up you go, the further in the direction of the curve you can see. Go lower and the curve blocks what you're observing.

Any information that is explained to the flat-earther goes through one ear and out the other
