I believe I met David in 2009. I must have his business card lying around somewhere at home (complete with Virgin Galactic logo if I recall correctly!).
If it's the same chap, then I can say that he was a really friendly, down to earth guy, and gave me a lot of encouragement with my own flying career. As far as I recall he also flies warbirds for the Shuttleworth Collection. And all-round nice guy.
