Well I probably owe my life to wearing a helmet. In 1972 I had a mid air collision which can be seen on the GA Safety Sense leaflet 13 "Collision avoidance" on the CAA GA website. I was wearing an RAF Mark 1 bonedome with a cloth inner. The helmet was badly broken but my skull was not. I sustained mild concussion only. It was during an airshow and I have worn head protection while flying in airshows since the mid 1960's. Presently I have an Alpha mark 10 retrofitted with an ANR mod kit plus two US helmets, one helicopter type and one fast jet fighter type modified with civil electrics and boom mikes. They are expensive but you only have one skull so you just have to make a choice. I did long ago.
Having said that I doubt if more than 15% of my 13,000 plus hours have been flown wearing head protection. In an air taxi Aztec or a flying club spamcan it would be a bit out of place.....!!!
