When I was working for Australian Air Charters in 1976 I was cross-hired to BizJets to fly that aircraft on the Queenstown run. My logbook shows about 5 trips. I subsequently met the pilot of that accident three years later but I've forgotten his name. He reversed the let-down and descended in the opposite direction to the plate and just flew into the ground. His dramatic description of events was bone chilling. What I remember most was his tale of the incredible silence when everything came to a stop. Leaves were fluttering down into the cockpit from the torn cockpit roof which pealed back.
What made me laugh was the first words spoken by the passenger down the back, "!!!! eh". Very lucky and proof you always stand a chance if the aeroplane is still flying and not stalled or doing a VMCA demonstration.
