Apologies for this turning into a 2-33 rant that even jumped threads. The typical US trainer was brought up in another post to which I replied with a question. Have never tried to let go of the 2-33 stick on tow, thought others might have. Seems to me a mistake similar to that is what it takes to start an upset. Rare, yes. Fortunately so is the towplane upset.
Last experience in low tow 2-33 flying was landings on tow. It's a lot of stick pressure. But compared to modern ships it seems a lot of control pressure to do anything.
Like too many of us, I have lost a friend to a towplane upset. Many in Region 2 knew him.
Certainly in strong wave - and strong rotor - low tow provides a larger window to keep the towplane visible in. An invisible towplane should not have a glider attached.
My personal apprehension about low tow near the ground is from a low level, low tow accident I feel would have had a different outcome with another 20 or so feet of altitude to see and use the safe option. Instead the outcome was of the worst variety.
