My gliding club has a Pawnee and anybody who did a Split S in it would be fired on the spot................
BPF,
I agree. A student and I in a Blanik were nearly killed by a tow-pilot doing that when he
thought the rope had released. We ended up accelerating nearly vertically downwards. Using two-hands, I managed to release going through about 100 kts, whereupon the Blanik did a stick-free 3G pullup, attempting to regain the trimmed speed of 50 kts!
I used up the fourth of my nine-lives on that occasion. Luckily, no more since.
