A sticker details the exact location of one of more than 2,200 cassettes of stained glass in the U.S. Air Force Academy Cadet Chapel in Colorado Springs, Colorado, May 11, 2020. The sticker will allow for the replacement of glass in the exact same location once major renovations on the chapel are complete. The chapel closed in early September 2019 to allow for necessary repairs and is estimated to be completed in 2024. (U.S. Air Force photo by Trevor Cokley)
