G'day 601. I'd want to know how well the UAV flies after having one of its rotors smashed and the thing turned on its side. Maybe it'd plummet straight down. Maybe it wouldn't. I'd want to know how well it recovers from a hit to the electronic control box. IE when the 'link' is cut. Then do that with the rotor out. Then a couple of rotors out.
We aren't talking about a first flight of a type. We're talking about flying a known type into a completely hostile environment. It's basically a combat zone but one with hundreds of thousands of people hanging around as close as possible to an exclusion zone that was designed for fireworks, not errant UAVs.
Fly just above the fireworks, beside them, heck, even from below and to the side. Through them though?
