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:
There are many levels of atmosphere around the Earth as you move from ground into space, 5 levels as we have modeled them. The first is the Troposphere, which reaches out ~ 20,000 feet - 65,600 feet (6-20 km) from ground level. Mt. Everest is about this high. Most planes, etc remain in this level. The second is the Stratosphere, which reaches out ~ 164,000 feet (50 km). Weather balloons are able to reach this high into atmosphere. The third is the Mesosphere, which reaches ~ 279,000 feet (85 km) from ground level. This is generally where meteors burn up and can be seen from the ground.
