Thirty years ago I was on a flight that encountered strong but brief turbulence. The seatbelt light had just gone out and I was about to unbuckle when Pow! My arms were flung upward, completely extended over my head, and unbuckled passengers bounced around with everything loose in the mix - “Chicken flyin’ everywhere around the plane…” as the song goes. That was all I needed for me to keep my seatbelt on whenever seated ever since. I suppose it was a learning experience not everybody has been privileged to learn, and it’s not like passengers have not been warned.
