Jim,
So you are suggesting to measure the force on the tow tope, assuming
it would rise dramatically if the spoiler is open?
Sounds like a good idea, but:
1) Will it trigger in a ground launch? Won't opening the spoilers
REDUCE the load?
2) Would it trigger when the handle is just unlocked, and the spoilers
aren't actually out (yet)?

What about the towhook? Magnetic sensor? where? How? Other ideas

Install a strain gauge internal to the fuselage right up against the hook
mount. Get Peter Masak to design a simple circuit that trips an electronic
relay when the strain exceeds a certain amount. Knowing Peter, it should take
him less than an hour.
