U.S. Air Force Airman 1st Class Johnathan Kropke, 7th Operations Support Squadron ground radar apprentice, speaks during the 2015 Big Country Innovation Challenge June 26, 2015, at Dyess Air Force Base, Texas. As one of the presenters, Kropke suggested transferring paper technical orders to mobile tablets in his section, so all files could be available electronically. He placed third in the challenge and was awarded $1,600 to purchase the tablets. (U.S. Air Force photo by Senior Airman Kedesha Pennant/Released)
