Staff Sgt. Steve Morris, a metals technician with the 433rd Airlift Wing's Metals Technology Shop, demonstrates the shop's computer numerical control mill center, which manufactures components for the C-5A Galaxy that have long since become unavailable. Demonstration was done for visitors from insurance giant USAA, who visited the M-TECH shop and other sites to learn about the missions performed by the 433rd Airlift Wing.
