Members of the U.S. Air Force Seven Summits Challenge team pose for a photo on Mt. Everest. The team climbed Mt. Everest, reaching the summit on May 20, 2013. The team is an independent group of Airmen who, through the sport of mountain climbing, aim to spread goodwill about the Air Force. The team is aptly named for its self-imposed challenge to climb the highest peak on each of the world’s continents. Since 2005, the team has scaled Mount Elbrus in Europe, Mount Kilimanjaro in Africa, Mount Aconcagua in South America, Mount McKinley in North America, Mt. Vinson in Antarctica, Mount Kosciuszko in Australia, and finally, signifying the completion of their goal, Mount Everest in Asia. (Courtesy Photo)
