This made me wonder how much engineering/materials time was spent on reducing drag due to texture, fairings and so on - in fact, how significant that actually was.
Would rrivets, wheel bay doors etc have any sort of significant impact on drag? Does localised flow disruption actually reduce drag under some circumstances?
I remember the paint job underneath was as rough as the proverbial bear's rear. The painters were forever trying to keep it nice and slick after the leaking fuel had done it's magic.
