U.S. Army National Guard Chief Warrant Officer 4 Clifford Bauman, while at Langley Air Force Base, Va., Aug. 22, 2013, reflects on the boots, gloves and hat he wore during search and rescue missions at the Pentagon, Washington, D.C., after the Sept. 11, 2001 attacks. After the missions were over, Bauman placed the work gear in closet and did not touch them again until 12 years later. (U.S. Air Force photo illustration by Staff Sgt. Jarad A. Denton/Released)
