Senior Master Sgt. Michael Ross, 592nd Special Operations Maintenance Squadron, carries an American flag up a flight of stairs during a 9/11 Memorial Stair Climb event held at Duke Field, Fla., Sept. 10. The 24-hour climb began at 8:46 a.m. with the 919th Special Operations Wing commander walking the flag up the outside stairwell of the base’s billeting facility. Wing Airmen took turns walking the flag up and down the stairwell the entire day until it was delivered to a firefighter and security forces color guard at 8:46 a.m. the next morning for a 9/11 Remembrance ceremony. More than 115 Airmen carried the flag throughout the day and night for a total of more than 207,000 steps. (U.S. Air Force photo/Tech. Sgt. Sam King)
