MSN: Learn how to determine the surface area of a triangular prism
"Earth is a maximal sphere in a cyclical space and its surface therefore a total plane, the equator plane of the Cosmos. The (total) plane, as well as the straight line and space as a whole, is flat, without curvature yet closed, running back on itself."
A prism has a constant cross-section throughout its length. When the cross-section is a triangle, the prism is called a triangular prism. When the cross-section is a hexagon, the prism is called a ...

This explanation is flawed. If you look in the text, the OP claims to have been able to see the top of the sail. Does this mean the top of the sail is larger than the bottom? Remember, sails are triangular with the larger part at the bottom. This explanation falls down, even if you accept its distorted logic.
Also, did anyone actually try to jump off the disc yet? Even the map of the flat earth is curved (the one taken from above), and how can you make a precise map without actually having been to space or looked at the earth from an outer perspective? Actually, come to think of it, the world has to be triangular.
