Thank you JenCluse - confessions are never easy - you have my admiration.
Well before my time at the Port Lincoln Flying Club they also trained in Chipmunks. I believe a similar (fatal ?) accident happened near Tumby Bay but I have no details.
Having done more research it appears I was wrong. Both accidents (yes two within a fortnight near Tumby Bay one of which had one fatality) were not as a result of spinning occurrences. Both however make interesting reading.
