What an amazing man. I had the pleasure of meeting him many years ago. My Wife at the time was a Wanaka girl and went to school with one of the Wallis boys.
So holidays with the inlaws always ended up with some sort of contact with that family.
I recall they had a little fox terrier that used to fly with whoever was flying on the day.
My sister-in-law (at that time) also looked after him after the Spitfire accident, she was a head injury nurse.
