I note your usual childish sniping, Pull what.... Do grow up.
Actually I learned to fly in 1968 under the tutelage of Ron Campbell, so the instructors didn't need to crib from some industry book - they taught as Ron required. They were also checked by HQ CFS as they taught RAF Scholarship holders, such as the 6 of us on my course.
And we didn't do pre-stalling / spinning checks before practising steep turns.
