Avweb [0] has a bit more concise report of the story:

>On June 28, Chilean prosecutors allege that Guo submitted a false flight plan at Carlos Ibáñez del Campo Airport in Punta Arenas, indicating he would fly over the city. However, authorities claim he deviated from this plan without notification, continuing toward Antarctica and landing at Lieutenant Rodolfo Marsh Base in Chilean Antarctic territory.

>Prosecutors allege that Guo violated “multiple national and international regulations” by altering his flight path without prior approval and touching down on a portion of Antarctica claimed by Chile.

Also, this is a 675 nm (1250 km) trip, with 529 nm (980 km) over open ocean during the southern winter. [1] Still within range of a 182, but yikes.

Doing this in a single-engine Cessna was gutsy.

My question for people who know about this stuff: how hard would it have been to get permission to land in Antarctica?
