Matt, great that you have successful patents. I actually have two of my own. But you probably need to answer your own question, namely when is there enough existing technology? The schweizer and tost have been working successfully for more than 60 years with millions of tows to their credit. Maybe the problem is the modern guy behind the stick and not the “antiquated” technology. Maybe the problem needs to be addressed at the source and not put another bandaid on the festering wound. Taking your analogy and applying it to it’s ridiculous conclusion; why have any aviation training at all? Lets just use engineering to solve every problem of airmanship. Folks the problem is not with the metal (tow hitch) it is with the “mental”!

As for operating with no tow hitch at all, let me tell you, there are guys I would be totally comfortable with towing them with the rope tied to my tail spring (been there-done that), and there are others I wouldn’t tow with the most highly engineered “fail safe” contraption you could possibly design.
