Not saying you didn't. I am saying that in 1978 alot of the housing estates around Roborough weren't there and PFLs were an option. First solos haven't happened for at least the last 15 years.
I can't speak for what will happen at Yeovilton, but I suspect that as grading solos aren't a requirement, a busy airfield like Yeovilton would not be the place for them.
