Used to pax in a B200 that used to have that happen quite regularly. Charlie at Norfolk Island Airlines and seem to remember KTE got it once or twice. Checked the pics on the current AVweb news and it is exactly the same as experienced. Never saw it happen but flew many hours staring at the screen. Unnerving to look at
Methinks the pilot has not many hours on type to not have witnessed it before. However, if having never seen it before it would surely lead to a panic that your world is about to explode.
