From an expat Aussie. I'm desperately saddend by this dreadful accident. In line with this thread I thought I point out that in the UK all turbine public transport, which includes air med here, are required to be 2 crew ops and not merely 2 pilots, there is a difference. I believe the night circling approach in marginal wx to be about the most demanding there is and demands a 2 crew op. My sincere condolences to the family of a professional aviator who lost his life in the service of his fellow man in my home state and best wishes for a speedy recovery to the flight sister.
