No one (that I know of) holds Antarctica is a wall.
Some hold there is a wall around what we call the Antarctic.
The path traveled goes nowhere near where those who hold there is a wall say it is. You seem to expect going no where near an object you'd be able to see that object. That's pretty silly, even for a globe trotter.
people have traveled Antartica pretty thouroughly. Crossed it from every direction by now.
You have not actually said what you believe, which is fair. But I have met some dozens of flatties that think either
A) You cant actually get to antartica due to CIA snipers or something
B) There is an actual wall at antartica, althought they did not say if it was antartica itself, or at the "outskirts" of it . . which would be the center of a round earth S Pole.
Geometrically speaking, if the pole was an actual physical tall pole, and you extended it in the way a typical Flat Earth Maps, displays, then that pole would display as a wall a couple of thousand Km long. So maybe thats what they are talking about?
According to this guess as to what the flat earth looks like, assuming the circumference of earth is not in dispute, Antarctica is 24873 miles long.
If the wall was gaurded by snipers, you would beed about 30 000 snipers sitting along the length of the wall. Then another spotter for each one. And maybe give them 8 hour shifts, we now have 180 000 snipers and spotters, one station every mile.
You may need a team of chefs, kitchens, medical ext to keep them alive. So another 10 000 or so. 200 000 personelle to gaurd the wall.
mmm. . . maybe it will be easier with missile or artillary systems, the only issue is, radar does not easily pick up people with little equipment, so anyone can ski past. But if you have one missile or canon every 100miles, you can do better with 250 stations. Artillary needs about 6 persons per canon, and radar is about the same. 3 shifts times 250 stations is much better at 9000 soldiers.
So maybe the CIA or whoever can gaurd the wall with 10 000 soldiers. Im sure they are trustworthy and will never speak out about their time camping at negative 30'C for months on end.
