A jack-screw bracket for a KC-135 Stratotanker is displayed inside a metals milling machine during a demonstration at Fairchild Air Force Base, Washington, Nov. 19, 2020. Rather than using the outdated process to create the bracket, 92nd Maintenance Squadron aircraft metals technology Airmen used their training and expertise to design a 3D model of the bracket, and program a milling machine to create the first prototype.
