Wow. The article states that the "plane" separated from the prop. I guess you could look at it that way.
The whole story raises so many questions: Prop strike a few months before, replaced prop, but what about engine internals,ie crank shaft? What happens to balance when prop separates since it is so far forward of cg. Was the cause the prop separating or did he fall victim to the "impossible" turn. What were his options straight ahead? ( I always check the surrounding areas of a new airport on google earth to see what's out there in the event of a problem). Guess they will figure it out.
Poor guy, can't imagine the shock of that happening and wonder if I could hold it together if it happened to me.
When you lose a prop it's like feathering one. BUT BETTER! there is no drag at all!
The imposable turn becomes more like a good idea when you get rid of all that drag.
Now there is prob a freak-out factor when he did lose it!
