Remember serving with a Flt Lt at London Centre, 2 rows of ribbons and a Pathfinder eagle. Thoroughly nice chap however, whenever any representatives from Germany were due to visit, either the Wg Cdr or Gp Capt would have a gentle word and the watch roster would be quietly changed to put him on 'gardening leave' for the day. We never heard the reasons why and we wouldn't dream of asking.
