An Airman from the 23d Civil Engineer Squadron calculates dimensions for a bridge, May 31, 2019, in Sainte-Mère-Église, France. The engineers provided structural support for the Commemoration of D-Day 75 by repairing and building bridges that were used to access hard-to-reach areas of a parachute drop zone. As part of the commemoration, parachutists from across the Department of Defense performed the same jumps their predecessors did on D-Day. (U.S. Air Force photo by Airman 1st Class Hayden Legg)
