This time is about an employee of Lockheed Martin, which provides logistical support for station’s activity. A Canadian Twin Otter plane operated by the Canadian firm Kenn Borek Air, Ltd.made the 1,500-mile, nine-hour trip from a British base on the Antarctic peninsula. Monday was the first day of winter in the Southern Hemisphere. There are very special conditions. The temperature Tuesday morning at the South Pole station was minus 75 degrees. Cold affects planes including fuel, batteries and hydraulics. This plane can fly in temperatures as low as minus 103 degrees. At the station, planes must land in the dark on compact snow. The station has a doctor, a physician’s assistant and is connected to doctors in the U.S. for consults but sometimes the problems can’t be solved locally.
