On the issue of aerodrome security....there are a couple of posters from Australia critical of NZ aerodrome security. It is almost impossible to stop someone like this obtaining an aircraft. He had a photo id card and would have had access airside if there was a fence there. How could NZ or even Australia.....or even the US....fence every airstrip which has the possibility of a plane being overnighted? The americans don't do it as it is not practical. Once a fence is there you need a lot of manpower to police it. There are literally dozens of incidents around the world each year including one recently in Sydney where the international airports have had someone scale the fence and board a vacant jet. It would cost billions of dollars and there is no way that the industry could sustain that cost. It is about risk mitigation not elimination. Where someone has a will, they will find a way. Before I am labelled soft, it does not mean we should not do everything in our power to stop this. Who knows what the answer is? Imobilisers like cars? Runway obstructions? The list could go on but to eliminate this we would almost have to shut down an airport and thus remove it from being an option in an emergency.
