Many thanks
Gentle merged people, I entered this unknown area of PPRuNe for reasons which I seem to have forgotten, my attention having been caught by this thread which I have enjoyed hugely - my eyes have wept tears of mirth! I have treated it like a fine malt and restricted myself to four pages only so, as Arnie said, I'll be back.
My sincere thanks to all contributors. (It's better than JB!)
