So just to get back on topic the proof that you cant travel to Antarctica is:
United Nations military, allegedly, shoots down Chilean military jet on way to a military base in Antarctica.
18 Chilean military passengers missing presumed dead.
2 engineering private contractors, enroute to carry out maintenance work on military base, missing presumed dead.
1 student, enroute to take up internship at Antarctica base, missing presumed dead.
1 photographer, regular visitor to said base for over a decade, missing presumed dead.
I'm struggling to see it if I'm honest. Reading the link suggests to me, that movement to and from Antarctica is regular and this appears to be an accident.
As much as I naturally distrust governments, destroying very expensive equipment, killing at least 21 of their own personnel, to stop a couple of people, they invited, from checking their fuses, is a bit of a leap??
