I flew with Mark Miller (and his father) at Duxford in their restored DH89 Rapide, painted up in WWII colours of Scottish Airways (G-AGJG). They very kindly offered me a jolly when I was exploring the hangars during one of my many visits during layovers. We slowly rattled about the English countryside checking out a couple of disused airfields. Very enjoyable afternoon followed by a cup of tea in the canteen. The aeroplane was immaculate, looked brand new. As an Aeronautical Engineer/pilot and total 'DH enthusiast' I was astounded by his wealth of knowledge in all things de Havilland.
Shame such expertise is not part of this investigation. (Maybe it should be).
