I agree with that Wally 2. I certainly would not like to see the type of aircraft a pilot could fly based on the licence or rating he held. After all many VFR pilots just don't need an IFR rating along with all the expense of staying current etc. I know of one well known aerobatic pilot who can fly the backsides off most of us who doesn't hold one for the above reason, not to mention the dozens of instructors in the same boat.
If that sort of thing started occuring what next? All IFR flights must be 2 crew? No passenger carrying IFR except high capacity RPT? It would never end.
The guy made a poor judgement with tragic consequences, we can all learn from this and hopefully not repeat it but at least he did that himself against the rules. Unlike the tragic fatality at 2RN where the pilots were following the procedure for entering a GAAP laid down by the regulators years ago and in my view unwittingly creating a dangerous situation just waiting to happen.
