I was in Syd recently & had some time to spare down at Circular Quay I was amazed at the amount of choppers flying low over the bridge/harbour which I assume is a re selected heli route for the tourists. After reading this thread & some of the comments I'd be hesitant to step aboard a Robbo (of which there where many on the day) to do one of these flights.
Just an observation that's all.
I don't know a lot about choppers other than the toy ones I play with but the risk of an unfortunate outcome due engine failure for me personally would be to high, each to their own I guess.
I hope the families of those lost are doing their best in this time of terrible sadness.
