Stack was the one who agreed with RonJ of 191 miles of curvature.

Tower A is on the east coast and set at sea level and tower B is on the west coast and set at sea level. According to Stack and Ronj, the center of Australia is 191 miles above the base of the towers A and B.

Stack provided the following conclusion.

On a Globe Earth, the center point of Australia would actually be 191 miles above sea level of towers A and B.

**And the elevation of Marla, Australia (near central Australia) would be 1076’ above Earth’s circular curve as dedicated. **The highest point above the east and west coast waters at center would be 191 miles plus 1076 feet.

In reality, in real life, tower A is on the east coast and set at sea level and tower B is on the west coast and set at sea level.

**According to elevation charts and topographical maps the highest point near center Australia that’s above the base of towers of A and B is only 1076 feet and not 191 plus miles **Australia does not belong to a Globe Earth. No land mass on this Earth has surface measurements of a sphere. Our Earth has horizontal oceans with landmasses sticking up out of the water.

**If Earth were a Ball, elevation points would have to be established above and with Earth’s circular curve at different points for engineering purposes. ** The worlds languages would include a meaning for a curved horizon, like Curvizon. Our would world be much different.

I know many will not agree, but the conclusion is Globe Earth believers cannot prove Earth's landmass has any curvature because topographical maps and engineering will prove them wrong every day.
