THIS WAS NOT RA Aus
Well it was once, and as close as you can get.
The question is, what are we going to do about it?
Certainly, "better training" isn't going to do it.
Maybe do psych evaluations early on in flying training and if they say this person might do this kind of stuff, cease training and blacklist them?
When registrations lapse, send out inspectors to hide in the bushes and see if the aircraft is being flown or not?
Make aircraft (parts) dealers report "suspicious" purchases of spare parts?
Stupid is as stupid does and just like more people have the ability to afford flight with affordable RA-Aus aircraft and training, naturally, you also get more stupid people.
The only thing to stop it is people dobbing others in, regardless of the organisation the originally registered with.
