REFLECTOR: Landing Gear Retract Prevention

[Richard J. Gentil]

Does anyone have a solution to keep the landing gear from retracting on 
the ground should someone accidentally select the up position on while 
the aircraft is on the ground.

Without drag braces, etc. I did not see an easy way to wire in a circuit 
interruption short of something tied to airspeed. (Sort of like what the 
old Piper Arrows used to do.)
