As a fellow kiwi I mourn the loss of this extraodinary man. I only had the pleasure of meeting him and his late son for a relatively brief moment, but they were both as friendly and down-to-earth as anyone could wish for!
From an aviation point of view I had the pleasure of watching his displays in Wanaka and the UK and you could not see a more professional display of warbird flying, which I am sure will be endorsed by those that were lucky enough to work more closely with him!
RIP Ray. You have done NZ proud.
