Strange disk found 6 km from an unknown base in Antarctica

Two interesting objects in the middle of nowhere in Antarctica.

First object seems to be a structure/base (50 x 30 meters) and the second object is a circular object with a diameter of 30 meters.


The distance between the UFO disk and the base is just 6 km.


Why they have built a base in such remote area and the circular object could be a crashed UFO?

The crashed disk is part of a secret project and the test/operation is guided from that base or the UFO disk is extraterrestrial and the base has been set up to investigate the UFO?
