On 23 January, 1973, a Cessna 150G aircraft registered VH-KPH disappeared whilst on a
travel flight from Latrobe Valley, Victoria, to Merimbula, New South Wales and no trace has been found
of the aircraft or its occupants.
An intense air, sea and land search commenced at first light
on the next day and continued until 13 February 1973. Civil and military aircraft involved in the search
flew 166 hours and covered an area in excess of 8000 square miles, within which the high probability
areas were searched many times. Twenty-five sighting and hearing reports were investigated but no
trace was found of the aircraft or its occupants.
