I think you will find the cameraman concerned will be interviewed by ATSB.
I do not know if the cause was weight related, weight may have nothing to do with it, all I know is that he pulled the pin when he saw it was an R44 piloted by the executive producer. According to him, it was going to be too cramped for him to work well, and the gear he was to use was heavy.
Both this guy and another one I know are Award winning ACS members and do a fair amount of aerial work from time to time and they have decided to refuse some of what they consider to be the more dangerous requests that are routinely made to camera men.
Their view is that you really want a turbine, preferably a Twin turbine with a professional pilot, with a bit of room to get good results in safety.
