U.S. Air Force Airmen assigned to the 435th Construction Training Squadron refurbish a WWII aircraft engine display at a memorial in Picauville, France, April 30, 2019. Years of weathering rendered the display unpresentable. The 435th CTS team replaced the translucent case around the display with a new one, allowing people to see the aircraft engine inside.
