I am not a flat earthe either but I travel frequently. I have flown over the Arctic countless times... I have never flown over the Antarctic even if it made sense to do so.

I also have a very wealthy friend, him and his team invented a cancer screening test using feces that can 'predict' cancer before you get, he's worth millions and millions. He has been to the Antarctic and he said the level of control was extreme. I've seen his pics so I know he's been there.

The only evidence that I have seen for flat earth is that whole thing about flight paths. That shit is shady. Might be something there, probably not flat earth though.
