I have. Have you? The results are not consistent with the globe model, try it yourself.
Antarctica. Pic related. This map, known as the Azimuthal equidistant projection, is the official map used by United States Geological Survey, because it's the only accurate map of the earth. It's also used for the (((UN))) flag, go figure.
Thanks to the Antarctic treaty, the largest, most successful and longest lasting international treaty in history, no one is allowed to actually go all the way to the south pole and beyond. The history of the treaty, and what happened before and after is where things get really interesting.
If the earth was indeed flat, and as some suspect, surrounded by some sort of dome as described in Christianity, Islam, Judaism, Buddhism, and Hinduism, among others, well.. you see where I am going with this right? People would no longer need blind faith to believe in religion, and this would be a threat to the current power structures.
Don't take my word for it. Look into the history of the Antarctic Treaty, Admiral Byrd, Operation High-Jump, and Operation Fish Bowl. Also look into the math of the globe model, and how often 666 shows up. We all know how much Jews love to hide 666 in plain sight to mock us. Look at the map, and consider how it would effect travel, then look into commercial flight patterns. It all lines up with a flat earth.
There's so much to go over it would need it's own thread which would get shilled to death on Holla Forums by people spamming shill, back to x, fringe, etc.
