A helmet fit to fight
Lt. Col. Randal Efferson, center, and Staff Sgt. Lemuel Velazquez, left, explain to evaluators how the F-35 Lightning II helmet is custom fit to the pilot’s head. Velazquez said the key elements of the helmet are fully incorporated so the pilot can more effectively focus on his tasks and avoid cockpit distractions. Efferson is the deputy operations group commander, 33rd Fighter Wing and Velazquez is an aircrew flight technician, 33rd Operations Support Squadron. (U.S. Air Force photo/Major Karen Roganov)
