Maj. Wes Robinson, an aircrew member in the 123rd Airlift Wing, pauses for a moment of silence at the Kentucky Air National Guard Base in Louisville, Ky., on Sept. 11, 2011. The reflection was part of the unit's 10th anniversary observance of the 9/11 terrorist attacks on the United States. (U.S. Air Force photo by Tech. Sgt. Dennis Flora)
