"The Guyra crash in '93 was distraction/disorientation at night during the recovery from a loft attack on a simulated target. Unsure of the previous one at Tenterfield, but it could have been something similar."
There were OZ TV documentaries (probably ABC) about at least one accident when RAAF cause was disputed by families. Perhaps that is an avenue to explore.
