Absolutely no curvature of the earth can be seen. And the camera does a 360 turnaroundâ¦ The horizon is always at the eye-level. Logically, on a ball-earth, the horizon should be gradually lower as we go up in the air. The curvature of the earth should be seen far under 110 000 feets according to the Earth Globe theory. Open your eyes and see the evidence.
A spacecraft in a geostationary orbit (at an altitude of 35,786 kilometers) can see the surface up to 81 degrees away from its position. But at 81 degrees away it would be on the horizon as seen from the surface. A more practically useful limit for communications is about 75 degrees (blue solid line).
