I was visiting (socially) a friend stationed at RAF Church Fenton in the early 80's, then the home of 7 FTS, a Jet Provost T3/T5 equipped basic Flying Training School. He was a bit distracted when I arrived as they had just heard that a JP had gone in with fatal results for the pilot, whom he described as "one of the Vulcan cross-over lot." From that I gather that there were specific slots on the Basic FTS's for some of these folk as the Vulcan was being withdrawn, as the Refresher Flying School at Manby that would have done this sort of thing in my day had wound up with the closure of Manby and moved as a much smaller outfit to Leeming.
