At Catterick around 1965 a chap who had been chopped from pilot training turned up to start his Junior Regiment Officers' Course in one of those zip-up Bomber Command thingies, complete with regiment flashes. He was sent back to the mess to change and told to get rid of it ASAP. Another time a chap appeared in his no 2 complete with boots and anklets, web. Once again somebody had a not so quiet word with him, and he never appeared in that rig again.
