WASHINGTON (AP) — In an international effort, a Canadian-owned Twin Otter turboprop plane started the 1,500-mile flight to Rothera, a British station on the Antarctic peninsula, said Peter West, spokesman for the National Science Foundation, which runs the polar station for the United States. It's a nine to 10-hour flight, which the crew made from Rothera on Tuesday to get to the South Pole.
Once the sick patient and the crew — a pilot, co-pilot, flight engineer and medical worker — rest, they will then fly off Antarctica for medical attention that could not be provided on the remote continent.
West said at least one worker and possibly two — support crew employed by logistics contractor Lockheed Martin — had to be evacuated. The agency won't identify the sick workers or their conditions, citing medical privacy.
Normally planes don't use the polar outpost from February to October because of the dangers of flying in the pitch dark and cold. Wednesday it was minus 75 degrees at the South Pole (minus 60 Celsius), according to the station's webcam and weather gauges. The first day of winter in the Southern Hemisphere was Monday — the sun will not rise at the South Pole till the first day of spring in September.
The extreme cold affects a lot of things on planes, including fuel, which needs to be warmed before takeoff, batteries and hydraulics, West said. The Twin Otter can fly in temperatures as low as minus 103 degrees (minus 75 degrees Celsius), he said.
"The air and Antarctica are unforgiving environments and punishes any slackness very hard," said Tim Stockings, operations director at the British Antarctic Survey in London. "If you are complacent it will bite you."
"Things can change very quickly down there" with ice from clouds, high winds and snow, he said.
The National Science Foundation decided last week to mount the rescue operation because one staffer needed medical care that can't be provided there. The station has a doctor, a physician's assistant and is connected to doctors in the U.S. for consults, West said. There are 48 people — 39 men and nine women — at the station.
There have been three emergency evacuations from the Amundsen-Scott station since 1999. The 1999 flight, which was done in Antarctic spring with slightly better conditions, rescued the station's doctor, Jerri Nielsen, who had breast cancer and had been treating herself. Rescues were done in 2001 and 2003, both for gallbladder problems.
Scientists have had a station at the South Pole since 1956. It does astronomy, physics and environmental science with telescopes, seismographs and instruments that monitor the atmosphere. The foundation runs two other science stations in Antarctica.
