I'm talking about for instance this frame

The white thing seems to go really close to the pentagon, it seems improbable that's a perspective thing to me.

If the white thing in this shot is smoke, why wouldn't it be smoke in the previous frame but a car reflection? I may have missed the specific argument for that.

For the sake of argument, I assume the white is smoke if it is not a reflection, not the actual plane itself. That is also my opinion, but leave it for this just as a "for the sake of argument thing". We don't need to drag a third option into this, as it is irrelevant for this tiny sub-discussion and only confusing.
