Parked next to three BA 380's the other day and noticed how filthy the fuselages looked - similar to museum aircraft parked externally for years with black water marks beneath many of the cabin windows. Not something I've noticed in such a relatively young aircraft nor other active types for that matter.
As far as spoilers and speed brakes are concerned...they're effectively the same thing doing a similar job - multiple panels mounted on the upper surface of the wings that extend into the relative airflow on selection (manually or automatically) and although the cockpit selector is placarded 'Speed Brakes', this is really only a description of their airborne function as not all of the panels extend during flight. With WoW's, all surfaces extend and collectively are described as 'Spoilers'
