I’ve been towing for 35 years and have had kitting incidents, all with the schweizer hitch, and mostly pawnee’s. You can believe I am paying serious attention the first 500 ft of every tow!
I only had one instance of s schweizer hitch not releasing immediately. A 2-33 kitted severely and I yanked that release almost immediately. I rolled hard left then yanked again and she released. I got the load pulling more sideways than upwards. Thankfully I had the altitude to make that radical move with my nose pointing 60degrees downward.
There are alot of idiot glider flyers out there. This incident was caused by a 800 hour flier who dropped his phone and tried to retreave it when we were about 500 ft agl.
