are you serious?
Totally. Happens not very often but still many times/ year all over the globe. I've seen one happening and I'm only on my 40's (gladly for myself from the ground).
Those turbines are not fail proof. And will never be.
If you KNOW this accident has nothing to do with engine you better contact Austrian accident investigators because I do think you know more than they do at this early stage.
