Another invisible thread. And EiaS, your videos are pretty good evidence for a flat Earth. In the one, it shows that trying to turn the Earth into a plane leads to massive distortions, such that Australia was significantly smaller than Greenland and Africa much much smaller than North America (when it's 1.24 times bigger IRL). And the second video shows airplanes traveling along the Great Circle--the most fuel-efficient way to travel across a globe.
