Staff Sgt. Edward Bellus, an HH-60 maintainer at Kadena AB, Japan, pulls out a barrel-nut from the bench-stock, Aug.10, 2010. His idea of putting a sealant around this $20 barrel-nut expanded the life-span of the helicopter’s $450,000 main gear-box. The idea earned him $10,000 through the base’s Innovative Development through Employee Awareness program. (U.S. Air Force Photo/Tech. Sgt. Mike Tateishi)
