It was keenly felt long before 2014 (recall the movie ?) – some 6 decades ago, during the Cold War years.
Great strides were being made in aeronautical engineering, and flying machines of all imaginable shapes and sizes were launched in rapid-fire succession, each faster than the preceding one. Mach 1 was exceeded on 14th October 1947, followed quickly by Mach 2 and then Mach 3 by the second half of 1966. That was 3 times the speed of sound.
The Lockheed SR-71 with twin turbo-ram jets was the fastest of them all at 3,540km/h, while the North American XB-70 bomber (with 6 engines) reached 3,309km/h.
In 1970, the Soviets came out with its MiG-25 which could attain Mach 3.2 in short bursts (but the engines rpms were red-lined at Mach 2.8)
Those were the days when speed was king.
