Dewey Back, a 365th Training Squadron avionics instructor supervisor, demonstrates the 3D capaibilities of a tablet and smart TV at Sheppard Air Force Base, Texas, March 27, 2018. Back and others have been working the past couple years to bring the lower-cost, high-tech tools to the classroom but have yet been able to do so after hitting a couple road blocks. For their efforts, the squadron was recognized with the Continuum of Learn Innovation Adapt Award during the Air Education and Training Command Senior Leaders Conference at Vandenberg AFB, Calif., on March 21.
