Sparks fly as an U.S. Air Force Airman welds a piece of angle iron to the frame of a new airplane hangar in Clarksdale, Miss., June 30, 2015. Reservists within the 301st and 307th Civil Engineering Squadrons worked together on the city's airport as part of the Innovative Readiness Training initiative, an Air Force Reserve Command program that helps underserved communities while simultaneously providing real-world training for troops.
