Hi, I too had my log book at Civil at YMMB which according to Richard Gross ( Civil, Tooradin then RVAC ) all the log books on the shelves had gone to god.
I was under instruction there in 1978 and flew VH-CGR which interesting enough ended up in the golf course due to carby icing. This happened only an hour after my second lesson...
Naturally my logbook from that time is priceless to me as I was only 16 years. I worked scrubbing the planes down during the September school holidays and was given one hours tuition for every week worked. My flight instructor was ex Airforce pilot so to me it’s a piece of history, my history.
Im hoping it might turn up day in an antique shop or better still someone has rescued all the log books that Civil Flying School management should have guarded. ( Bib Stilwell )
