The SR-71, here shown in its A-12 variant, is the most beautiful design object of the 20th Century. It was a burst of raw vision, literally conceived within a dream, and built with the lovely precision of a Faberge egg. Fragile as an egg, it’s skin consisted of hundreds of intersecting geometric panels, allowing the plane to flex and expand as the airframe heated up. It looked like a panther and it moved like one.
