Where I used to instruct in SA we had 2 ppl's kill themselves + pax when they went spinning. I believe it gives some ppl's the idea to impress friends with a semi-aerobatic flight. In all my time flying I have never spun by accident nor seen a student come close. Most times when I have spun in C152+PA28 we had to attempt them more than once often without success. I firmly believe we should concentrate on stall/spin avoidance rather than showing them a new way to kill themselves.
