Air Force Materiel Command Commander Gen. Donald Hoffman sews a stitch into the National 9/11 Flag during a ceremony at the National Museum of the U.S. Air Force prior to the AFMC Freedom's Call Tattoo June 24, 2011. The flag was flying near the World Trade Center in New York City Sept. 11, 2001, and was all but destroyed by the terrorist attacks. Now on a 50-state tour, the flag is being stitched back together at each location. The Ohio patch to the flag came from a flag flown outside the AFMC Headquarters building. Assisting General Hoffman was Carolyn Deters of the New York Says Thank You Foundation. (U.S. Air Force photo/Ron Fry)
