Presidential departure
President Barack Obama waves as he walks toward Air Force One at the 911th Airlift Wing, July 06, 2012. The departure from the base was part of the President’s first bus tour of the campaign season, which began with a day of events in Ohio and then concluded the following day at Carnegie Mellon University in Pittsburgh, Pa. At the base he left behind his campaign bus and boarded Air Force One, which was headed back to Washington D.C. (U.S. Air Force Photo by Tech. Sgt. Ralph Van Houtem/Released)
