Y.O.Y.
I feel as if i'm feeding a troll, but l do intensely dislike the way in which you use the phrase "Utopian Engineering Era" in an almost sneering manner and which I consider offensive. You are, in modern parlance "dissing'" people that I personally knew to be good, conscientious engineers who provided a service second to none by comparison with the apparent lack of engineering professionalism shown by the Serco engineers and the incompetence of the uniformed people who were supposed to oversee the work on behalf of the RAF.
To answer your question AFAIR MGSP North was winding down when I was posted in late '83
