Agree with your comments. What I’d found seemed to be a pretty good and appropriate depiction of clear air turbulence associated with a jet stream. Right up until I apparently ‘broke up’ mid flight. Although there have been some very nasty incidents caused by turbulence I’m not aware of any total loss accidents associated with CAT in modern times.
So “bug” or “Feature”? Don’t know - but I fly with ‘Stress causes damage’ set to ‘off’ these days!
