Actually CASA and its regulatory predecessors all have blood on their hands. I know Leadsled claims the US GA accident rate is something like half of what ours is so we really should just adopt the US regs and operating doctrines forthwith before we kill any more people unnecessarily.
Also remember the whole ultralight thing that started south west of Sydney in the mid 1970s? The Regulator didn't enforce the law but neither did it bring those folks into the aviation community by promulgating some simpler regulation for basic pilot licences and US style Experimental category where bitter lessons that had been written in blood over the last 70 years at the time could be passed on. How many did they kill?
