Martin Butler - Guest Speaker 
Martin Butler was the guest speaker at our last dinner meeting. Martin, an ex-pilot has an interest in aviation history in New Zealand and talked about the first flights of the Walsh brothers. His interest in aviation also led him to research the mystery of 2 planes being stored in the North Head tunnels which in turn led to the possibility of there being more tunnels containing military history. However, disappointingly he has found there is a real resistance from authorities to allow further exploration so the mystery goes on.
An interesting and thought-provoking presentation which led to many questions from members
