In reply to Tony Naylor:
Wow, what a find, thanks for posting this. I've watched it through twice (and some bits more than that!), and I think the film in itself is excellent, with a nice preamble about the technical aspects etc. Then the interview...so moving...."Oh! It's me!" gets me every time; and the heartfelt, "every pilot should fly a spitfire at least once".
Folks, catch it while you can- it is up on utube for limited time only.
