As for the picture of the smoke cloud, this plane had enough fuel still on board to fly two thirds of the way across the USA. There is nowhere near enough smoke for that amount of fuel. The picture is therefore questionable.

Smoke is a product of incomplete combustion. A really roaring fire wouldn't produce much more smoke (it might even produce less) than a small one.
