To be fair in Antarctica territorial ownership is a bit strange, as I understand it a lot of countries don't recognise Antarctic claims in general and those that do tend to do so on a mutual basis. The British, Chilean, and Argentine claims considerably overlap as well which further complicates the matter.

Filing false flight plans and make unapproved landings at military-operated bases in territory with conflicting claims of three different countries is, in general, even dumber than doing it in territory claimed by only one country.
