第52航空团一架为尝试登顶麦金利山的登山者运送装备的 CH-47F“支奴干”直升机沿阿拉斯加山脉飞返。(A CH-47F helicopter from D Company, 1st Battalion, 52d Aviation Regiment, flies along the Alaska Range April 27, 2015, on the way back to Talkeetna from the 7,000-foot high base camp for climbers attempting to summit Mount McKinley. Soldiers and Chinooks from the D/1-52d "Sugar Bears" made short work of delivering several thousand pounds of equipment to base camps at 7,000 and 14,000 feet for the 2015 climbing season, saving money and time for the National Park Service and gaining invaluable experience operating at altitudes and in terrain not available for training missions outside Alaska.)
