Respect your opinion CS, but "IMO, both he and atc contributed to the accident." is a rash statement. ATC clearly wasn't aware of the severity of the developing situation, and its possible that the PIC had a fault with the oxygen supple or system - we don't know.
FWIW the aircraft N900KN ferried through Prestwick on delivery on 14 March this year. A friend sent me a picture of it at PIK but won't post as copyright isn't mine.
