@osint613: This fighter jet helmet stops working if the pilot gets a haircut The F-35 helmet is built from a laser scan of the pilot's skull. It lets them see through the floor of the jet at 1,200 mph and fire missiles by looking at the target. But gain five pounds and it needs a full refit. The most advanced weapons program in history, defeated by a haircut. #f35 #militarytech #fighterjet #aviation #military
