Can we agree that this whole smoke color argument is pointless and does not advance the "truther" cause? You do agree Temp can not be determined by smoke color, right?Smoke itself is incomplete combustion. Black smoke has different causes. Heavy black smoke with attendant flames suggests some petroleum product-based (hydrocarbon) fire. Without attendant flames, it suggests that it's either just started or it's struggling or smouldering. Heavy volumes of other-coloured smoke without attendant flames also suggests smouldering.
