Maybe the PIC should have zig-zagged until he crossed the coast clear of any ground structure, then ditched it in the outback on a saltpan somewhere, clear of all obstacles of course. Then the ATSB could relocate a team to investigate the airframe for hairline cracks in the airframe. 3 years later, when that investigation is done, they can investigate the incident itself. So I reckon the final report should be done by 2029-ish. In the meantime, CASA can ban any civil ops in close formation. Australians have proved they will blindly do what they are told despite facts/evidence etc.
Everybody will be kept safe by CASA, and they will like it.
