AndrewR, there is only one statistic that counts. The rate of VFR into IMC accidents per thousand hours flying or per cycle of Angel Flight vs. private ops and charter and airlines. That statistic didn’t show Angel Flight was anymore or less dangerous than normal GA ops.
......So ATSB invented a new one: the alleged rate of safety “occurrences” which did - making the startling claim AF was seven times more dangerous, which is utter lying, cheating bull****.
To put it another way, it’s as if you stated that all Volvo drivers were dangerous compared to others because they had a higher rate of parking fines.
