This year marks the 40th anniversaries of two of the greatest achievements in manned flight. In 1976, US military pilot Eldon W. Joersz set the still-standing airspeed record of 2,193.2 mph in the Lockheed SR-71 “Blackbird.” That same year, the Concorde introduced the world to supersonic commercial travel with the first passenger flights to break the sound barrier.
