people who travel from the north pole, and continue traveling, down all the way past south america, continuing straight, actually reach the south pole...
to say that they only "think" they reached the South Pole, is not scientific... the distance from one edge of the Antarctic to the other Edge has been measured. people have crossed it. if they themselves have seen it with their own eyes, their own senses, their own empirical observations, then that in itself is evidence.
there is no evidence that the people who "actually made it were killed or silenced", but there is evidence to the contrary
People, when they discovered the earth was a globe, no longer had a fear for looking for the edge. they were free to cross antarctica on scientific expeditions, and they did, and now we all finally know.
the FE model with two poles is a Dual Earth Theory model, and both the Earth's are flat, and that theory doesn't work either because the upword force would cause both earth's to colide with one another.
the evidence doesn't have to be pictures... the evidence is simply people traveling there, and traveling across the Ice Wall (i.e. Antarctica). Using empirical observations. If you had enough money to fund your own trip, you could do it yourself.
