"but we can't simply say because you have taken it away it's less safe." Mmmm, if thats how it works then it seems to me you could reverse the whole argument about safety and say that just because CASA are over regulating the s&*t out of everything doesn't mean it's more safe...just means it's over regulated. In fact the amount of over regulation is kind of a sadistic "work of art", so convoluted, with regulation upon regulation, masses of manuals, that nobody will ever be able to fully grasp...
