I have fond memories of seeing Vampires in the mid 1970s. The Irish Air Corps operated six T55s up until 1976s. They were a common site in and around the Dublin area up until then. They always sounded a bit like a whistling kettle - especially when throttled back.
My Dad was an armourer in the RAF and he used to load the shells into the guns. I remembering him saying he disliked the Vampire as he had to lay on his back underneath the aircraft and haul the shells in lifting them off his chest.
