SR-71 Blackbird Vs Norton Commando


The Lockheed SR-71 is an advanced, long-range, Mach 3 strategic reconnaissance aircraft developed from the Lockheed A-12 and YF-12A aircraft by the Lockheed Skunk Works as a Black project. The SR-71 was unofficially named the Blackbird, and called the Habu by its crews, referring to an Okinawan species of pit viper.

Clarence "Kelly" Johnson was responsible for many of the design's innovative concepts. A defensive feature of the aircraft was its high speed and operating altitude, whereby, if a surface-to-air missile launch were detected, standard evasive action was simply to accelerate. The SR-71 line was in service from 1964 to 1998, with 12of the 32 aircraft being destroyed in accidents, though none were lost to enemy action.

The Norton Commando was the last twin piston-engined motorcycle produced by the Norton Motorcycle company. Their last production bikes used a twin-rotor Wankel engine.
During the ten years it was in production it was popular all over the world. In the United Kingdom it won the MCN "Machine of the Year" competition for five successive years from 1968-1972.

Some regard it as the British Motorcycle Industry's swansong, selling well from its introduction in 1967 through the end of the British bike industry as a commercial concern in the mid 1970s.
