Editing Avro Canada CF-105 Arrow (section)

===Cancellation===
The Arrow's cancellation was announced on 20 February 1959. The day became known as "Black Friday" in the Canadian aviation industry.<ref>Zuuring 1999, p.&nbsp;112.</ref> Diefenbaker claimed the decision was based on "a thorough examination" of threats and defensive measures, and the cost of defensive systems.<ref>{{cite book|editor-last= Godefroy|editor-first= Andrew B.|date= 2009|title= Projecting Power: Canada's Air Force 2035|url= http://airforceapp.forces.gc.ca/CFAWC/eLibrary/pubs/Projecting_Power-Canadas_Air_Force_2035_e.pdf|publisher= Canadian Forces Aerospace Warfare Centre|page= 68|isbn= 978-1-100-12396-7}}</ref> More specifically, the cost would have needed to be amortized over hundreds of manufactured models. At the time the trend was "away from conventional bombers" that the Avro Arrow could intercept and "towards atmospheric weapons like [[intercontinental ballistic missile]]s", according to Global News.<ref name="Hobson2013">{{cite news|last= Hobson|first= Elton|date= 25 March 2013|title= 55 years later, biggest question surrounding Avro Arrow remains "what if?"|url= http://globalnews.ca/news/427985/55-years-later-biggest-question-surrounding-avro-arrow-remains-what-if/|work= [[Global News]]}}</ref> As a result, the foreign demand for the Avro Arrow had declined substantially.<ref>{{cite book|editor-last= Boyne|editor-first= Walter J.|last= Cafferky|first= Shawn|date= 2002|title= Air Warfare: An International Encyclopedia|chapter= Avro Canada Aircraft (A.V.

The decision immediately put 14,528 Avro employees, as well as nearly 15,000 other employees in the Avro [[supply chain]] of outside suppliers, out of work.<ref>Stewart 1998, p.&nbsp;269; Peden 2003, p.&nbsp;157; {{cite news|last= Harrison|first= Mark|date= 23 February 1959|title= Diefenbaker surrenders our sovereignty?|work= [[Toronto Star|Toronto Daily Star]]|page= 1}}</ref> Declassified records show Avro management was caught unprepared by the suddenness of the announcement by the government; while executives were aware that the program was in jeopardy, they expected it to continue until the March review. It was widely believed during this lead-up to the review, the first Arrow Mk 2, RL-206, would be prepared for an attempt at both world speed and altitude records.<ref>Peden 2003, p.&nbsp;78.</ref>

An attempt was made to provide the completed Arrows to the [[National Research Council of Canada]] as high-speed test aircraft.<ref>Whitcomb 2002, p.&nbsp;202.</ref> The NRC refused, noting that without sufficient spare parts and maintenance, as well as qualified pilots, the NRC could make no use of them. A similar project initiated by the [[Royal Aircraft Establishment]] (Boscombe Down) had resulted in Avro vice-president (engineering) Jim Floyd's preparing a transatlantic ferry operation. This proposal, like others from the United States, was never realized.<ref>Shaw 1979, p.&nbsp;89.</ref>
