It wasn't fully typical but by no means unknown at that BFTS, at least in my experience in the late 1970s. I was surprised how many QFIs seemed to be non-volunteers for the job.
We had one particular individual with a very nasty reputation. I didn't fly with him for long before I got to the situation where I spent much of my airborne time with him more or less wanting to punch his lights out. I went to the flight commander (Hinch) and asked for an instructor change. I was told "Well, someone's got to fly with him".
I obviously wasn't the first to ask but I did get an instructor change.
