That old saw has been gone over again and again and again. It is not the military’s doing, but the lobbying and success of the commercial aviation operators in convincing governments across the country to prohibit the military from conducting fire bucketing (even on DND property, to put out range fires and the like) so as to maximize their own revenue. If commercial bucketing operators in the Okanagan asked you why the military didn’t bucket, they were either junior enough in their respective organizations to legitimately not know the answer, or old enough to know better. Based on the commercial fire operators’ efforts to maximize own profit water under that bridge, the RCAF removed the Griffon’s Bambi bucket from its very early service, never to be used much past its initial certification, so guess what? The ‘experts’ were right. The Griffon currently does not operate with a Bambi bucket.
Would be interested to see your reference as to which aviation experts were similarly saying the Griffon couldn’t fly in Afghanistan. I call BS on that.
