Twin Otter, dal Canada???? Se me ne sto in Groenlandia e mi viene l'appendicite, l'aereo lo fanno arrivare dal Cile?
Non c'era nessuno più vicino?

c'era un motivo preciso per cui hanno dovuto prendere gli Twin Otter

Qui e' spiegato meglio

Flying Otters

Most jet fuel freezes at temperatures about 30 degrees warmer than the winter average at the station. There are also no paved runways. There is only ice, as far as the eye can see. Actually, the ice stretches far beyond what the eye can see. The Antarctic ice sheet is about one and a half times the size of the continental United States, and it’s more than 9,000 feet thick at the pole. The plane needs to land on the ice and snow itself—with skis.

Kenn Borek Air, Ltd., is a Canadian firm contracted by the National Science Foundation to conduct these rare emergency flights. They have Twin Otters, planes that satisfy all of the extreme requirements for the evacuation. “This particular aircraft is about the only one that can withstand the temperature regimes at the height of the austral winter, but even then we’re very careful,” Falkner explains. The Canadian firm dispatched two Twin Otters: One to conduct the rescue, the other to sit at the edge of the continent in case something goes wrong.

The flight to the South Pole takes at least five days, depending on the cooperation of the weather. Neither the plane nor the pilot can fly the whole way without stopping. Once it arrives at the research station, the plane will pick up the scientist whose emergency forced the NSF’s hand. Where they bring their doubtlessly unhappy cargo depends on the nature of the emergency and, of course, what the weather looks like along the route.

The NSF isn’t the only one doing cost-benefit analyses when it comes to the wintering at Amundsen-Scott. Every year, about fifty people volunteer for exile in the center of Earth’s largest desert, and each of them has done their own calculus. The cold and the isolation bring their own scientific rewards; astronomical and atmospheric research conducted during the Antarctic night can be done nowhere else in the world. “Every day you can walk outside and see something new,” says Jensen. “And you might even be the only person seeing it.” The benefits, whether scientific, professional, or personal, outweigh the risks.

cavoli bisogna che ci vado prima o poi ..... Ma non ci sono additivi per carburanti? In Siberia da quel che ho capito nel diesel ci mettono il cherosene al posto della paraffina. Ci saranno additivi pure per il kerosene? Magari la Vodka?
