A piano burns after being set alight as part of a Royal Air Force tradition both to honor the memory of the 13 U.S. service members who lost their lives in the Kabul airport bombing in Afghanistan in August, and to celebrate the end of a successful flying and fiscal year at Royal Air Force Mildenhall, England, Oct. 1, 2021. Claims behind the tradition include stories that it reportedly started during World War II to honor fallen pilots. (U.S. Air Force photo by Karen Abeyasekere)
