The glide ratio of an auto-rotating helicopter is not great; not a very hard target aerodynamically. The glide ratio is not going to be great if all 36 engines are out but I'd expect crash landing as a glider it should be totally doable and probably easier than auto rotating a helicopter (nose down to keep the speed up, flare at the right moment). And of course installing some parachutes on it is probably going to be a thing as well. Of course that scenario is not great for either this thing or a helicopter in a dense city.
