About flights over South Pole:

"New Zealand's flagship airline plans to fly planes to Antarctica that would land on an ice runway."
So they will be building run ways there.
". If successful, it would operate two more charter flights during the upcoming Antarctic summer season. Planes would leave from Christchurch and land on the Pegasus runway on the Ross Ice Shelf, a trip of 2,090 nautical miles that takes about five hours.
Unlike existing military flights, the Air New Zealand planes could return, in good conditions, without the need for expensive and complicated refuelling.
The flights have been chartered by Antarctica New Zealand, the agency that runs the country's Antarctic programme. Flights would also carry American scientists as the US works collaboratively with the South Pacific nation in Antarctica."
So it looks like Antarctica is real.
