Rather than judge what we do not know (his skills except as reported by the press !HAH!), why not take a moment to wish his loved ones well.
THEN, after that, we, as pilots, can discuss what might have happened without assuming he was a dumb guy who bought a turbine doctor killer. Because if that was all it was, there is nothing to learn and nothing to discuss.... unless you are trying to prove your hooha is bigger.
Single pilot, IFR, in ice is dicey. Been there, done that, refused many. Crashes in that environment remind me if faced with it, take a moment, think, and decide ... do I really want to take the risk.
