Staff Sgt. James Turnbull, right, 41st Helicopter Maintenance Unit crew chief, and Col. Dan Walls, 23d Wing commander, pose for a photo during a black letter ceremony Aug. 21, 2020, at Moody Air Force Base, Georgia. The 41st HMU launched a “black letter” HH-60G Pave Hawk, a helicopter with zero discrepancies from nose to tail, inside and out. It has been three years since the 41st HMU achieved their last black letter, a significant accomplishment in the maintenance community. (U.S. Air Force photo by Senior Airman Erick Requadt)
