The Avro Arrow is the most painful story in Canadian technological history, and it has retained its grip on the national imagination for more than six decades because the facts support the mythology. Canada genuinely did build one of the most advanced military aircraft in the world in the late 1950s, and Canada genuinely did destroy it completely, and the people responsible genuinely did give reasons that were contested at the time and have been disputed ever since. The CF-105 Arrow began as a requirement issued in 1952 by the Royal Canadian Air Force, which needed an aircraft capable of intercepting Soviet nuclear bombers crossing the Arctic at high altitude and high speed. The specification was demanding: the aircraft had to fly faster than Mach 1.5, reach 15,000 metres, and carry an internal weapons bay. A.V. Roe Canada at Malton, Ontario accepted the contract and began design work that pushed the boundaries of contemporary aerospace engineering. The resulting aircraft was a large twin-engine delta-wing interceptor, 23 metres long, with a design speed in excess of Mach 2 at altitude. The aerodynamics, the fly-by-wire control system, and the integrated weapons system were all at the leading edge of what was technically possible in the mid-1950s. The Arrow RL-201 first flew on March 25 1958. Test pilot Jan Zurakowski reported it handled better than anticipated. Four more airframes followed. All five were flying and the program was expanding toward production when Prime Minister John Diefenbaker announced cancellation on February 20 1959. The reasons given included cost, a shift in strategic doctrine toward missiles rather than manned interceptors, and pressure from the United States to purchase American aircraft instead. Critics argued then, and have argued since, that each of these reasons was inadequate. The cost overruns were real but manageable.
