Among the first things we learn from the media about people like Bill Gates and Mark Zuckerberg is that they dropped out of college, and Albert Einstein did badly at school -- doesn't even matter if it's true or not! I don't know where this silliness comes from, but it's not usually intended to be derogatory or have any real relationship to the story being reported at all.
And you're right, you don't need to have graduated highschool to know this was stupid and dangerous.
Being a high school drop-out is the reason he was killed. If he had been to a 4 year course in Mechanical engineering, he would be exposed to a lot of knowledge about the complexities of building machines
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 worlds best engineers with Billions of dollars in multi-year budgets, who know about and exposed to a lot of knowledge about "complexities of building machines"...even they fall short.

Spot the difference?
The engineers of Columbia are probably still alive after that monumental fuck up. Did anyone question their credentials? Education? What high school they went to? What modules they took on their mech engineering classes?
The hypocrisy of attributing a failure to a lack of education is morally inept at best, and disingenuos at worst.
But my fear is more base. My fear is that the man is from a third world country and that your answer might be drawing an already unfair conclusion from that fact. I hope my fears are wrong and you are just being objectively pessimistic.
EDIT> I mean, before he got himself killed.
Education does not neccesarily prevent accidents. Even spacecraft, built by the best engineers in the world, with the best materials, tested for years, routinely fail and sometimes get people killed after spending 100s of millions of dollars.
