Senior Airman Richard McComb, 28th Maintenance Squadron aircraft structural maintenance journeyman, drills a hole through a nutplate hydroline bracket in the air structural maintenance building at Ellsworth Air Force Base, S.D., July 26, 2012. The bracket prevents the hydroline from rubbing against other aircraft parts during in flight turbulence. (U.S. Air Force photo by Airman 1st Class Anania Tekurio/Released)
