Hell that's probably less than 15nm up the valley from base - just a local jolly, but given the amount of tiger country lurking thereabouts, had a witness not given them a starting point they could quite easily have missed the wreck.
Makes you think, I may have to be a little more diligent about carrying my ipad and running ozrunways for every flight out of the circuit; I understand they can delve into your account and follow your tracks if requested by AMSA (and CASA no doubt....) At the very least that would cut down the time spent searching for the bits should I deck it somewhere.
