What happened
The twin engine airplane departed Sydney-Mascot bound for Wagga Wagga Airport (RAAF Forest Hill) but failed to arrive. The aircraft subsequently disappeared from radar and communication contact. Large-scale air and ground search operations were immediately launched to locate the missing machine and its occupants. Despite these extensive efforts, no trace of the airplane or any of the personnel on board was ever recovered. Investigators believe the aircraft likely crashed in the Burragorang Valley region. It is possible that the wreckage became submerged beneath the waters of Warragamba Dam, which would explain why physical evidence has not been found.
Findings
The specific cause of the disappearance remains unconfirmed due to the lack of recovered wreckage or debris. The primary conclusion drawn from the search operations is that the aircraft likely met its fate in the Burragorang Valley area. The potential submersion under Warragamba Dam is cited as a plausible explanation for the total absence of physical traces during the investigation.
