I've been refraining from saying you don't know what you're talking about here. The fact is, you don't, but I don't mean that as a criticism. I daresay you speak for thousands of non-pilots,
Indeed, I do not - and that
is why I asked the question. Thank you, and others, for answering it.
TonyR, My question did relate more to the space under discussion, Hertfordshire, and I should have made that clearer. But I have no idea where 'CAS' is, so please enlighten me.
There is no need to use words like "you really are something" when I started the post 'non-pilot speaking'. I am glad to you enjoyed your flight and trust that you have many more but please refrain from insulting a person who is trying to understand an area of which they know little.
