Uncle Ian – I think you are correct that when all of us in Europe fall under J.A.R or more likely E.A.S.A rule for flight operations filming will revert to Aerial work. As far as I can make out we are the only country in the world that classes Filming as Commercial Air Transport. However by then it will probably be almost impossible to attach anything to a helicopter without a rain forest of paperwork and we will be grounded anyway.
