This thread needs a little balance. I don’t wear a helmet. Offshore, instructing, fires, corporate, utility. I wore one EMS ‘cause it was required by contract (at our cost). Awkward to pack around for carry-on only baggage when touring. Is it safer to wear one? Sure, I have a whole row of helmets on a shelf, one for kiteboarding, one for road biking, one for mountain biking, two for motorcycle, one for skiing, etc.etc. In today’s world they should just graft one on your head at birth and be done with it. I’d wear one in helicopters east coast offshore just for the comfort standing out on the deck with a November 40 knot gale and sideways sleet. Or SAR/EMS if I needed somewhere to hang the NVG. Otherwise just leave me and vast majority of pilots alone. And you can go ahead and wear one anytime you want, in a car, in a 172, walking down hardwood stairs in wool socks.....
