U.S. Air Force Airman 1st Class Da’Lon Kennedy, 86th Civil Engineer Squadron firefighter, rings a bell during a ceremony at Ramstein Air Base, Germany, Sept. 11, 2020. To symbolize the devotion of the firefighters who gave their lives during the Sept. 11 terrorist attacks, a signal of three rings, three times each, represents the end of their duties and that they will be going home.
