Its all a bonfire of vanities really, all this JAA/FAA stuff. The real crux, as always, is MONEY.
WWWs dream of protected market GA in the UK is fine but who can afford it? At the end of the day the US has a less stringent (and cheaper) system that works just fine. All this hoohaw about extra training for US PPLs is just pure snobbery. Get over it guys.
I've been to America numerous times (work and play) and you know, they're a lot like us. WWW, you should go, I can highly recommend it
