Hoffman tour
Gen. Donald Hoffman, commander of Air Force Materiel Command, and Tinker’s Jim Crofoot watch sheet metal mechanic Danny Humpula don protective gear in the 551st Commodities Maintenance Group’s B1 Stabilizer Shop, Bldg. 9001. During his two-day visit Oct. 13 and 14, the commander saw new sanding equipment that contains 98-99 percent of contaminants and is part of Tinker’s benchmark safety program.
