In fact, this is what woke up the FE community again. Modern consumer optics gave average people to see much further than what should be possible.

 

===Refraction===

Because we can see too far, beyond the "curve" of earth, science has refuted these observations stating it's due to refraction. Therefor what you are seeing is actually around the curve, but light is bending up magically so that it appears like the distant object is on a flat surface.

 

When observations of objects 20 miles away were made, refraction was their answer.<br>

When observations of objects 100 miles away were made, refraction was their answer.<br>

When observations of objects 700 miles away were made, silence was their answer.<br>

Using a "Curve Calculator" <ref name=CurveCalc></ref>, we can calculate the observer's height with the distant object's height and the distance the object is, to determine how much curve is between you and the target.

 

Sagitta is the height of an arc or segment <ref name=Sagitta ></ref>. If we can see over the bulge or sagitta of earth's curve that would be literally miles high, the explanation of refraction becomes laughable.
