Some time around 73-74 our squadron commander had a load of us into his office, told us he understood none of us had put in for the 'C', and virtually ordered us all to do it. As far as I recollect we all applied, and I think we all passed. Mind you it didn't do me any good as I came out on the great 1975-76 redundancy scheme - like to think I might have eventually have scraped a scraper, but it's all academic now.
