Two aircraft in the same airspace, Same weather at the same time. VH-AZC continues to a successful outcome, VH-MDX ends up in a situation beyond the capability of its PIC. Sounds like a good human factors study. Seems pilots can make the airspace work (que AZC), so money spent there would be wasted. Has there been any repeat in the past 30 years? Taxes would be best spent elsewhere.
Root cause would seem to be somewhere in the soft skills of decision making and knowledge and situational awareness. Have there been any other repeat accidents due to this in the past 30yrs? If you want to save that young family, perhaps effort could be put into finding better ways of teaching and encouraging skills that are the real reasons aircraft crash.
