harrym,
So now we're going to lose you to the Groves of Academe (but I do hope "Finale" doesn't mean exactly what it says, but if it does, then so be it; and I trust I speak for all of us on this noble Thread (and beyond), who've followed you along that rough and winding road which all of us who Gained their RAF Pilots' Brevet in WWII had to tread, in thanking you for your rivetting stories, and wishing you good fortune in the days which were to come.
But you will look in from time to time, won't you ? (all benefit from the Wisdom of the Ancients, and there aren't many of us left, you know).
Cheers, Danny.
