I know i should always keep the inspire in line of sight when flying. I was wondering: If DJI would bring out firmware that would allow to circle around a Point of Interest, wouldn't that object interfere with the signal between drone and controller (of v.v.) if the object sits between drone and pilot? If that object is higher than 20 meters and the signal would get lost, wouldn't that be asking for the drone to crash straight into that object on "Return to Home?" To some extend i guess the signal bends slightly around an object. Most likely the larger the object, or the further away, the larger the chance on loss of signal. What do you think is a good practice or a rule of thumb to stick to? Have you flown an standard-I1 arround objects: if so how far were they away from the controller and how big were they?
