The SR-71 Blackbird is nothing short of a design and engineering model. Produced in the early 1960's by Lockheed Martin, this jet maintains its record as the fastest manned aircraft in the world. Every part of this aircraft was designed purely to fulfill its function of traveling at extremely high speeds at high altitudes, and yet the result is this beautiful sculpture of organic lines contrasting with bladed edges, making it appear both elegant and extremely powerful.
