This is my thought as well. Not all drones (I hate that term, but that ship has sailed) have return to home or even fail safe operations.<p>Imagine, for a moment, someone triggering this while there&#x27;s a quad racing event going on. All of a sudden, you have between 3 and 5 unguided projectiles following unpredictable paths, usually with spectators present. All of them are also carrying a fairly nasty incendiary device (also known to laymen as a battery), which reacts poorly to being crashed.<p>Or a fly-in, where not only the quads, but all RC aircraft are affected. Some of those move at well over 100mph, and are filled with jet fuel.
