Evacuations from Antarctica are extremely rare. Conditions during the winter make it risky.

Updated at 6:30 a.m. ET

A small plane on a daring winter evacuation mission from the South Pole landed safely Wednesday night at Punta Arenas, Chile.

The National Science Foundation, which runs the Amundsen-Scott South Pole Station, says the Twin Otter rescue aircraft took off from the South Pole with two patients early Wednesday. It arrived at a British base 1,500 miles away shortly after 1 p.m. ET before continuing on to Chile.

The South Pole station is staffed year round, but normally nobody enters or leaves during the winter months, which corresponds to the North American summer. "It's mind-boggling how cold it gets down there," says Jerry Macala, who oversaw the first-ever evacuation from the station in 2001. Temperatures routinely drop below -70 Fahrenheit, and the C-130 transport aircraft used during the summer months cannot land, Macala tells Kelly McEvers on Wednesday's All Things Considered.

Macala says that landing a plane in the perpetual night is considered extremely dangerous. During the 2001 evacuation, he says, he instructed his crew to light oil drums along the runway to guide the plane in. But in the frigid Antarctic temperatures, the gasoline they used wouldn't ignite. "We had to use acetylene torches to light these things," he says.

When the plane was finally ready to take off, they discovered it had frozen to the ice. "Everybody pitched in, and we rocked the wings and hit the skis with big pieces of wood," he says. "Eventually, it broke loose."

Despite the risks — and a wind chill of -113 degrees Fahrenheit — Wednesday's evacuation flight appears to have gone smoothly. The NSF says a sick contractor was brought out, along with a second individual who was suffering from a medical condition. Details of the illnesses are being withheld owing to patient privacy concerns. The two workers will be treated at an undisclosed hospital.
