That would of course be the Tristar, that practically nobody else uses making it pretty identifiable, with a 3 foot tall ROYAL AIR FORCE, written along the side, when you are spending a fortune equipping the aircraft with DAS and the solar glint from the white paint may attract certain missiles?!?!? Oh and you are using your bright white shiney bird as a tanker in hostile environments where the white makes you stand out like the proverbial dogs....!
I cannot believe, in these days of instant mobile telecomms, that anyone still subscribes to the 'make it as much like a civil airliner as possible' theory. However I also cannot believe that they have had someone polishing the nacelles and the wings - not much solar glint off them I guess!!
