Is there anything to suggest that your average Piper or Cessna would have survived this iceing encounter?
If not, then what exactly is your point?
I'm sure the police could tell us how many people died last week in Ford Mondeos. Does that mean that Ford Mondeos are unsafe cars?
We all know that flying is a dangerous hobby. Flying into iceing conditions in a non-deiced aircraft is particularly dangerous, and not allowed. If you want to give your point any weight, you'll have to do better than simply state that there has been an accident in a Cirrus.
