What a weird way of looking at things. With that frame of mind, I could explain all the issues I've had ever. "Oh, I hit that wall on the way out from the parking? Too bad I didn't have a racing education, then it would have been prevented" and blame it on lack of education.

The reason he was killed was because the main rotor hit his head. It did so because it wasn't following safety precautions. None of that has anything to do with his formal education.

The main rotor hit his head -> Because it suffered a material/design/ structural failure -> Because design validation or material quality checks or weld quality NDT checks or bolt sizing or balancing or lateral vibration suppression or a million other things were not checked -> Because you need to know to do that, and those are taught in an engineering course.

Even if you know that, failures still happen all the time because as you state, there are thousand things that could go wrong and this task could be too much for a single person.
