I wonder if the You Tube video had a title like "A visit to the Barrier reef" and that there was music instead of a laugh track, if the pilot would ever have been prosecuted? I think not.
Needless to say, no cameras ever again on any aircraft Sunfish flies.
To put it another way; in my youth I worked at a chemical plant with a highly unionised workforce.
I remember learning "Tell 'em nothing". I suspect that pilots are now adopting that approach out of simple caution, knowing that any disclosure can result in prosecution.
Since getting out of the stock market I've been wavering about an aviation investment. Threads like this make it unlikely because the risk is too high since there is no consistent interpretation of the regulations. We are always guessing what CASA will accept.
