Helmets
"the risk involved still make flying as dangerous as rally driving"
If you feel that way maybe you should pack it in. Safer than driving and walking come to that.
I never wore a safety helmet as a kid nobody did and am not aware of any accidents that caused problems. My kids never wore them either.
And we climbed trees, without a saftey net.
You going to stop your kids going out in case they get hurt.
Lets all stay indoors all day in case we get hurt. It is easy to pick a particular case where a helmet MAY have helped as well as cases where they would not.
Fly comfortable!
