Is it true that airplanes don't fly over Antarctica because there is a wall separating our world from a hidden world controlled by rich elites like the Rothschild family? No, that's not true: There are flights to Antarctica, but the reason many planes don't fly over Antarctica is that all current commercial routes don't need to cross the South Pole.
The claim appeared on TikTok (archived here) by @omiso.channel on February 10, 2024. The narrator says there is a frozen wall in Antarctica that can't be crossed (translated from Japanese to English by Lead Stories staff):
There's a frozen wall that's forbidden to enter and fly over ... You can't go in because there's a hidden world where people who control us live in ...
This is what the post looked like on TikTok at the time of writing:

There is no frozen wall in Antarctica that aircraft cannot fly over, as many have flown either to or over the continent for military or research purposes (archived here). Several videos of airplanes flying over the South Pole have been documented and uploaded to the Internet and do not show a frozen wall as described in the claim. The closest thing to a visible "wall" that the video claims exists are protruding icebergs and hills. In addition, efforts have been made to make travel to Antarctica more accessible to the public (archived here).

Airplane routes don't often cross the South Pole, not because of a mysterious wall separating our world from another, but because there's simply no need to do so (archived here). Due to the low visibility and undeveloped infrastructure, flying over Antarctica is extremely difficult. The lack of infrastructure for commercial flights in Antarctica makes it unnecessary and difficult for many larger planes to land as the main human settlement on the continent serves primarily as a research facility (archived here).
