The DC-6 based at Salzburg is owned by Red Bull not just sponsered and is to be used for company coporate hospitality type events. It may appear at one or two shows but as I understand it from one of the Captains of the aircraft they do not intend to display it as an airshow aircraft.
As for the paint job, nice job in keeping with the style that 6s were originally painted in but also the Red Bull coporate colours. I would prefer to see the Sea Vixen in it's old colours or Navy scheme but I prefer to see it flying looking as it does than not at all.
