Sigh.

Why can't the Earth be modelled accurately on a flat map (Do not fold, spindle, or mutilate) if it was, itself, flat?

Why can't you get the distances between cities worldwide to be modelled correctly on a flat map?

How can there be direct flights between Africa, South America, and Australia on a flat map? The distances become far too great for flights that exist.

Why are great Circle routes used in long-distance aircraft navigation?

Why do Foucault pendulums precess?

Why are all the other planets we can observe spheres?

Why is the shadow of the Earth when the Moon is eclipsed a sphere?

Why do constellations in the Southern Hemisphere circle a different point that the constellations in the Northern hemisphere on a flat Earth?

Heck, why are there different Southern Constellations on a flat Earth?

And lastly, because I've seen the curve, firsthand, when I used to fly. But I don't expect you to believe me.
