Adm. James "Sandy" Winnefeld, Vice Chairman of the Joint Chiefs of Staff, speaks during the 9-11 Commemoration Ceremony held in the center courtyard of the Pentagon today. The Admiral, Secretary of Defense, Leon Panetta, and Jeff Parness, the founder of the New York Says Thank You Foundation, addressed the crowd and concluded the ceremony with the Defense Secretary and Vice Chairman each sewing a stitch onto the flag. Shortly after, the crowd lined up and also each sewed a stitch, adding another piece of history to the flag. DoD photo by Air Force Master Sgt. Chuck Marsh.
