You can absolutely see the earth's curvature if you're at altitude, particularly over the ocean in a plane. At sea level, you can only see about 3 miles. The average angle of human vision is somewhere between 120Âº and 140Âº; more if you count the whole image your brain builds up as your eyes move. The curvature of the horizon can be found with:
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).
