I'd have thought it was pretty obvious to anyone following the conversation that I was talking about New Zealand.
I was talking about an IFR clearance.
As for the clown comment once again if you'd been reading the thread you'd know it is illegal to fly in IMC in NZ unless you're on an IFR plan. Anyone doing so who isn't on an IFR plan is an idiot. The term clown was being very complimentary. What you want to call them in the UK is up to you.
I know it's legal to fly IMC without a plan in the UK, however I don't consider it very smart, so yes, I'd probably still call them a clown or something similar.
