Chronus - That pilot did a fair chunk of my command line training. A lovely guy. What was really good was on one trip was his gasp of "Oh God" when after avoiding one particularly nasty Cb, an even bigger one was waiting round the corner. He thought he'd let me go in to the little one to teach me a lesson. I was able to teach him one. The escape route was clear to me before we went in - what I didn't do was explain my thinking beforehand. One all, good instruction.
