I'm curious as to how many clubs or tow pilots have really trained and cut a glider loose? It takes a bit of time to react to the situation and if you've never trained or experienced it the time is even greater.
Most tow pilots have talked about it but never experienced it in the heat of the moment.
We pull an unexpected release on our glider students. When do the tug pilots get the same unexpected training?

At one of the clubs I frequent they drop the rope in the grass on landing. So at least the tug pilot is used to reaching for the release and becomes comfortable with its location.
