Going through the ground at the south pole

[dioxhunt]

I made a plane to go to the south pole and when landing on one of the shores of the south pole, I just went through it, no colition at all, I kept falling until I hit the sea level.

Also when loading a quicksave my wings and several other parts, like landing gears or intakes would fall off
