What has ethics got to do with flying a plane (or aircraft for the fanatical)? Seems to me the pilots did their job well under trying conditions. Their only responsibility is to get the pax and freight safely from A to B, everything else being legal of course.
As for the social problems – well we can thank our elected officials for doing the job we pay them to do. That is to keep the problem swept under the carpet with welfare payments and preferential treatment so we can sleep better at night.
The only solution starts with abolishing any welfare (by some transitional means) and integrating the aboriginal population by recognising them as just Australians of aboriginal descent. No different to you or me. Until this happens we’ll be reading articles like this in the paper for decades to come – that’s if there are any “indigenous brethren” left.
