Destination airport:
Crashed 01/09/67, Williamtown NSW. During low level aerobactic display practice while the pilot was practicing for Air Force Week. The aircraft crashed into the ground and hit the bitumen road that runs along the base and ended up several hundred metres inside the Hunter District Water Board land. Pilot, Flying Officer A.Karpys, killed.

Comment by John McNair:
"The Aircraft was in level flight at the time and probably experienced "Roll Coupling".
I arrived at Williamtown 2OCU not that long after this incident and the story goes that there was some discussion the night before between several Pilots about how many barrel rolls could be attained in a Mirage before roll coupling became untenable. Apparently the aircraft was at say no 3 when it became so unstable it plummeted into the road upside down. Seems to be Pilot error based on a bet. Other stuff told to me was not much left of the Pilot, and it was very close to married quarters. Plane was level but in an axial rotation ( barrel roll) manoeuver. John McNair"
