Andrasz - I submit that you are speaking with excessive certainty here.

I'm generally skeptical, too, and dismissed the video when it first came out, but as details of the crash have become clearer, I'm not as certain anymore.

To refute your absolute claims, I'd like to refer you to the following video which shows practice shoot-downs of drones by US Air National Guard planes.

In particular, look at the "kill" at 3:22 - the missile hit apparently releases and ignites a plume of fuel from the target drone, which initially burns brightly, and then turns into a puff of black smoke.
If you continue watching, for a while, there's only a small flame visible on the wreckage until a few seconds later when the flame gets larger and a visible trail of black smoke develops again.

This is by no means conclusive proof that the footage is real, but it refutes your very absolute claims that the black smoke is impossible under the conditions of the flight.

I'm still very skeptical of the reality of the footage, but I think your absolute rejection is based on shaky arguments.
