One BIG Point: If A turns-on on B, and B causes injury/damage to C, then B is protected, however if A gets sued by C and/or B, A is all on his own.
Very interesting, Hoss.
Hmmm.........I tried to picture this scenerio with people and events, rather than cold abstractions. Here's my short story (disclaimer: characters are fictional and not intended to portray any real persons)
Arnold A. majored in Political Science, and so lives with his parents and flips burgers at McDonalds to support his pattern flying addiction. One day Arnold arrives at the Jetero RC Club and unloads his pattern ship and flight box and prepares to bolt the wing the fuselage. He notices the left aileron is drooped, and in short order has the cause traced to a servo gear that has become stripped. Not a problem, there's a spare servo in the flightbox. After replacing the servo and linkage are removed/replaced, he flips on the radio to check that the servo travel and direction are okay. Leroy B. screams "I AIN'T GOT IT!!!" 2 seconds before his 1/3 scale Edge, which had just cleared the runway on takeoff, has barrel-rolled over the pilot station barrier and struck Horrace C. squarely in the back, crushing two vertebrae.
Fast forwarding a couple of month's we find Horrace C. in a courtroom, sitting in his wheelchair, while the matter of who is responsible for providing for his care for the rest of his life is being argued. Leroy B's lawyer successfully convinces the court there was no negligence on his part, hence no liability. Arnold A. is found to be 100% liable for injuries sustained by Horrace C.
Good thing the Jetero Club is AMA chartered, so Arnold was required to be an AMA member and thus covered by a $2.5 million liability policy, right?
