Yes, death by turbulence is rare, but there are dozens of serious injuries a year caused by turbulence in US air space alone. Hundreds a year, globally. We're not talking about a small graze or cut, we're talking head injuries, broken bones, life changing injuries. Costs US airlines half a billion dollars a year dealing with it in terms of payouts and maintenance costs. Why you think that doesn't apply to you is a strange take to me, but you do you.
