U.S. Air Force Col. Brian Hastings, 355th Fighter Wing vice commander, places a stitch in the National 9/11 Flag at a flag stitching ceremony held at the University of Arizona’s Centennial Hall in Tucson, Ariz., July 8. The National 9/11 Flag Tour is a grassroots effort to repair the 30-foot flag that hung across from the Twin Towers and was damaged during the Sept. 11 attacks. Retired flags from across the 50 states are being used in the restoration. (U.S. Air Force photo by Tech. Sgt. Russell Martin)
