I'd be a little cautious about detailing 'he flies his own jet' or some such nonsense. There is a huge difference between a guy that sits in the cockpit with his corporate pilot and a guy that flies himself around...or actually flies somewhere vs stays on the ground when the weather is iffy.
I mean I know airline pilots that won't go anywhere unless they are in an Airbus, so how far do they do in their C172,
No real threat of celebrities flying around their jets...takes years to get there and it's not happening so far on any real basis with out babysitters to 'help' them get around.
