"..that criticism of CAsA and of individual officers of CAsA is not acceptable".. to him.
Hey aroa, as you would be well aware, you're not quoting Skidmore here but Leadsled's opinion! This is a whole new level of self-fulfilling silliness.
The sentiment of the AOPA letter is good, all of the points are sound. The 'Skidmore quitting the organisation' issue and the dreamed-up malevolent motives being attributed to him by some posters are totally separate things.
At the very least it's a conflict of interest for him to be a member if he's also high up in the regulatory system, which could just as easily be his motive for resigning as some imaginary demonic desire to kill GA!
