He was my Chief when I first arrived at Lyneham and deserved the promotion more than anyone I have ever met (except for yourself obviously). Here we have a superb Chief with decades of dedicated service in the RAF who suddenly feels he wants no further part of engineering in the RAF.
You know as well as I do, he's not even in a minority.
The Chief deserves hearty congratulations anyway, and very best wishes for the future.
