The CO at Kirton when I went through was a Gwoop Captin Lerwell (thats how he said it) and his passing out address went something like "whether you be pilots, navigators or air lectrictwonic officers, 50% of you will be dead within the year and another 20% will be maimed for life, good luck chaps". As far as I know most of us (99 course) survived well beyond the forecast.
