Tim Gannon is promoted to the rank of first lieutenant by Capt. Mark Uberuaga at their second camp on Mount McKinley, Alaska, in 2008. As the team climbed on, just a short distance from the summit, they were treated to a surprise other team members had arranged: a roaring visit from the Air Force’s F-22 Raptor. In April of 2013, the team will attempt to climb to the summit of Mount Everest, the highest mountain in the world. (Courtesy photo)
