Flat Earth Theory / Re: Circle of a Sphere

What this fact does is refute one of the main false assumptions of FEers, namely, that one can tell what shape the earth is from ground level.  For positive proof of a globe earth, one need only look at a horizon distance chart (http://www.table-references.info/earth-table-distances.php).  The fact that one can see significantly further from a higher altitude proves the earth is a globe, for this is observable from any point on earth.  Engineers factor this effect into their surveying by C+R formulas (http://www.aboutcivil.org/curvature-and-refraction.html).

Flat Earth Theory / Circle of a Sphere

If one is standing at a point at which they can see the horizon as flat, 360 degrees around them, then this does not prove the earth is flat.  One would simply be looking at the 'circle of a sphere' on a globe earth. (https://en.wikipedia.org/wiki/Circle_of_a_sphere)
