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:
Diagram: For a given height above the surface of the earth we can compute the angle $\theta$ from $$\theta = \sin^{-1}\frac{R}{R+h}$$ And in order to see all that earth through a view port of diameter $d$, you need to be closer than distance $L$ from the outer part of the view port, so $$L < \frac{d}{2\tan\theta}$$ It should be clear from this ...
