An interesting and tragic thread.
I have read reports that the young man got out of the aircraft and immediately walked towards the spinning tail rotor. Not credible in my opinion.
I have read (many) reports that he left the helicopter, went to the terminal, then ran back for a selfie whilst people were telling him not to ( lots of corroboration of this). Absolutely believable of a rich young kid.
Regardless, the fact is that no law can fully legislate for stupidity, ignorance, or ego.
Given the subject’s background I suspect he thought he knew better, ignored the warnings from the ‘plebs, and got the inevitable result. In fact I bet that is what happened.
Do I know that for a fact? No, I was not there.
But I bet I am right.
