All trumped by cirrus taking off into thunderstorm though.
If that's the same Cirrus I heard about, that one was piloted by a gazzilion hours ex-airline captain that now runs the (GA and RA) school at Aldinga, I think he knows what he was doing!
(And might have taken off towards a thunderstorm, but I doubt he actually flew into it!)
To get back on topic, that is also the kind of school that cranks out very qualified pilots that with CTA training would no doubt put weekend GA pilots trained in the country to shame with their knowledge and skills when it comes to transitting Melbourne airspace. But I guess we won't know for now!
