Either that's fake or (at the risk of waking up Jocko) it's some kinda UFO camouflage.

I suppose it is conceivable that the UFO type tech stuff could generate such a cloud--though all their's I know about lack sharp angles like that.
Am reminded of an old Donald Duck comic wherein for rain making purposes, the Duck was taking a plane and shaping clouds with sharp angles to match the field boundaries. LOL.
