These jumpy house operators are being held to a higher standard than display pilots, which I think is exactly the opposite of what should be happening.
My thought too!
I wonder if the jumpy house operator followed the manual, did the soil tests, drove the anchor stakes in at the specified angle, just the right depth, and so forth.
Any pilot has a very specific set of instructions and limitations within which to operate. Excursion from those may be evident in the case of accident. The jumpy house operator might have thought they'd set everything up well, but did they have as well defined guidance for jumpy house set up and operation, as any pilot would for even a simple flight maneuver?
