The SR-71 Blackbird: Engineered in 1966. Still one of the fastest aircrafts ever (~2,200 mph). It could fly 85,000 ft high, close to the edge of space. An example of Sci-Fi in the past. 57 years ago we could engineer this level of greatness that is mindblowing, even today. Technology, namely hardware, should be much further along than it is right now.
