IF, I were doing BDA (while not conclusive), from the little info we do have and can see (which is not much), I’d say leaning toward PROBABLE, this aircraft was in tiny charred pieces before it hit the ground.
As well, I am leaning toward large debris field.
Notice at least one area, where the walls and manmade structures are intact, with lots of debris strune throughout the standing structures. This is strong indication of falling debris, vs lateral travelling debris.
And of course, the Obamanations good buddies in Iran would never do such a thing... /s
Have you had a chance to see the full clip? I dont know much about such things but Im pretty sure you are correct. Just before it hits there is a huge flare, not quite an explosion, that suggested to me that the fuel tank had ruptured or something. From that point forward Im sure that there were no people or an aircraft left just a spray of flaming char.
