That's not a fire (yet), looks more like it's dumping/injecting fuel unregulated or they didn't properly run a pickled engine prior to flight. All the above are not ideal, but unless you see a flame, it's not on fire. You'll f'ing know when it's on fire.
No they didn't, your first clue is the fact that it's intact. That tells you someone allowed them to have it. All of our drones have a multi level 'self-destruct' option. If it's in one piece, it's a gift from a traitor.
Images dropping out is as common as shills/slides so didn't even think anything of it. Jimbo, fix that shit!
