To elaborate. We're not saying that's the aircraft that has crashed.

Possible airborne command post to coordinate with ground units.
Doubtful. If you've ever seen a plane crash parts can go flying quite a distance from the crash site given momentum and angle of impact. Plus if it had been shot down it would have exploded in the air and small pieces would be strewn over a MUCH larger area.
