To my way of thinking, the pilot in question, even though he was potentially knowingly breaking the regulations, was the only one who had the local knowledge to successfully carry out the rescue. The outside helicopter had to abort because of weather, and no doubt lack of intimate local knowledge of the area the hunter was cast in.
It was stated in one of the reports that the pilot in question knew this area exceedingly well, having made many flights for DOC emptying rain gauges etc etc.
To then be charged after successfully carrying out a difficult rescue, because of a potential medical factor, which obviously had no affect on his flying ability, certainly makes one wonder as to CAA motives in bringing a prosecution
