I know that many old folks on here (myself included) are rightly very proud of what we achieved 30-odd years ago. Even back then I worked in one of the few parts of the RAF that flew 24/7 ops. However, at the time, the majority of the Service didn't. Now though, the Op commitment is far more widespread and harmony guides are often broken; it is probably not such a good time to take on extra work which impacts our Operational output - such as taking huge amounts of manpower to run (and secure) airshows.
