Airman 1st Class Randy Mullis, 47th Operations Support Squadron radar approach control operator, poses with the helmet that saved his life at Laughlin Air Force Base, Texas, Oct. 23, 2013. Recently, Mullis was thrown from his bike during an accident, landing head-first into a boulder near the road. According to the doctors that tended to Mullis, he would not have survived the crash if he was not wearing his helmet that day. (U.S. Air Force photo/Senior Airman John D. Partlow)
