   A small plane with two sick US workers arrived safely in Chile late Wednesday after leaving Antarctica in a daring rescue mission from a remote South Pole research station. After making a stop for a few hours at a British station on the edge of Antarctica, the two workers were flown to the southernmost Chilean city of Punta Arenas. In a chaotic two days of flying, the rescue team flew 3,000 miles roundtrip from the British station Rothera to pick up the workers at the US Amundsen-Scott station at the South Pole. "The two patients aboard will be transported to a medical facility that can provide a level of care that is not available at Amundsen-Scott," says a spokesperson. Normally planes don't go to the polar post from February to October because of the dangers of flying in the pitch-dark and cold. "Antarctica creates a hostile environment," says the operations director for the British Antarctic Survey. "If you're not careful, it'll come round and bite you."
