The safety record for this country... for what its worth.
"Excellent and unique" according to CASA.
"Ordinary" by world stats by more objective reseachers.
Why do we have a "good" record...notwithstanding with some unfortunate blemishes recently.
IMHO its because 99.99999% of aviators try their very best to stay alive, and try not to do anything knowingly unsafe or plain dumb.
Therefore, those that do.. become a statistic and into the Safety Digest.
You could bury most of CASA and the regs underground and the result would be the same.
Above ground most engineers will carefully maintain things, and most pilots will 'professionally' fly things....not because of CASA, but to keep their respective ar$es intact. Its the survival thing.
