There are many anecdotes surrounding David, here is on of my favourites….
David had been for a night out with his wife Helen; they were using their usual form of transport, a motorcycle. On the journey home David decided that he would do some observing, there was a meteor shower that evening and one of David’s interests was trying to photograph the spectrum of a meteor using a prism in front of the camera lens. On arriving home Helen went into the house and David went into the garden to set up is equipment which he stored in the garden shed. After few minutes Dave heard a voice from over the garden wall,” Good evening sir”, he turned to see a policeman. Dave realised some explaining would be needed. After describing that meteors were really particles of rock passing through the Earths atmosphere the policeman looked at Dave and said, “That would explain the crash helmet you are wearing then sir!”.
