A 9/11 memorial display of a firefighter suit sits unworn to represent the lives lost in a stairwell at Yokota Air Base, Japan, Sept. 9, 2022, during the annual 9/11 tower run. The tower run competition is a timed relay style event with four member teams or individuals. Each team member climbs nine flights of stairs while wearing a self-contained breathing apparatus air pack. The members go one at a time, rotating off and on until each member has climbed and descended the stairs three times. By the end, each team collectively climbed 110 floors, equivalent to the stairs climbed by first-responders at the World Trade Center during 9/11. (U.S. Air Force photo by Yasuo Osakabe)
