> how outrageous it is to dare to land on a slab of ice and rock

The particular “slab of ice and rock” that he landed on without permission after filing a false flight plan appears to be (while the story mentions only that it is a military base) a public airport operated by the Chilean air force, and the only airport on King George Island. (The name the article uses for the base is actually the name of the airport that is part of the base, the base has a different name.)

There's kind of a good reason for them to be touchy about people not following protocol with things like flight plans and landing permissions.

That makes way more sense.
