ivor,
sure schools in the UK won't mind having couple more students.
Those who can sell house in the UK or remortgage or get huge loan will train either way. Just not sure whether they wouldn't head to Australia, NZ or SA instead. Still cheaper than UK.
As for 'ailing', people here mention shortage of instructors in the UK. Maybe not every school, but if there's less guys coming back from Bristows with JAA papers and FI rating, there'd be less available instructors, right? I'm not talking about lucky guys with excess of 1000 hours or even spare cash for JAA IR(H) in Billund or wherever.
What about those who can't get enough cash for flying so much in the UK? Would they sacrifice another x years just to get it all done to JAA min hours for instructing, even with some hourbuilding in the US after PPL?
