Master Sgt. Steve Pakusch prepares to demonstrate how the Wolf Blending Scope is used to fix damaged compressor blades inside an aircraft hangar March 19, 2014, at Offutt Air Force Base, Neb. An adjustable grinding tool attached to a rod about three feet long is inserted through a one-inch port on the side of an aircraft engine, which allows Pakusch to grind down irregularities without removing the engine from the aircraft and taking it apart. Pakusch is the 55th Aerospace Maintenance Squadron production superintendent. (U.S. Air Force photo/Delanie Stafford)
