Ah yes Ron Campbell
I remeber 'wonderful' Ron Cambell I went to an instructor syposium with Campbell and a CAA examiner at Coventry in the 70s.
Campbell stood up half way through and opened a Birch and Bramson book at the spiining page and started to pull it a part saying it was dangerous. I think that must rank as the most unprofessional act i have ever seen in flying--i never thought much of him after that! what was more amazing is that Bramson and Cambell were both on the panel of examiners.
