Polar Bear swim
THULE AIR BASE, Greenland – Icebergs float on the horizon as 821st Air Base Group Airmen hold a polar bear swim Aug. 4 and 26 at the Thule AB Tug Boat Beach. The air temperature was 51 degrees, while the water was a scant 41 degrees. "It was a really unique experience,” said a chilled Staff Sgt. Neal Thompson, 821st Air Base Group Knowledge Operations Management. “It was definitely something that a lot of people are unable to do,” he said referring to his newly-earned title of Polar Bear. Thule AB is one of the six installations operated by the 21st Space Wing, and is located 750 miles north of the Arctic Circle. (U.S. Air Force photo/ Staff Sgt. Laura Vargas)
