Even by 2013 standards, Lockheed's SR-71 Blackbird is considered one of the most technically incredible aircraft ever made: flying nearly three times higher than an airliner, its pilots were made to wear spacesuits. It could quite literally outrun a bullet in straight flight. It evaded radar decades before the F-117 and B-2. And perhaps most incredibly of all, its skin was made entirely of titanium — which came mostly from the Soviet Union — at the height of the Cold War.
