And somehow they accomplished this without compasses working. Which later proved problematic in 1979:

You have a lot of trouble visualizing things don't you?

Now do you understand why you can pass over the North Pole but not the South?
But earth is a torus and that's why you can fly east and arrive where you started. The ice in your poles separates our isolated 6 continents from the neighboring 6 continents. Earth is way bigger/longer than they say. Only a select few individuals can move or communicate between "planets" in our toroidal ecosystem.
Like, earth is a cylinder and our North pole is touching the next earth's south pole, on and on in a great arching line.
Yes, that is one belief. But you can't just type a reply assuming everyone reading it knows that's what you were thinking. Where as the flat earth model is a little more self explanatory. Your theory also flies in the face of reality were flights do travel over the north pole.
When I typed my first comment it was tongue in cheek imagining earth as a snowglobe shape flat on the bottom and bulbous on the north half.
