Who ordered to destroye the Avro Arrow?

The decision to cancel the Avro Arrow program and destroy the aircraft was made by the Canadian government under Prime Minister John Diefenbaker in 1959. The cancellation was influenced by a combination of factors, including escalating costs, changing military priorities, and the shift towards missile defense systems. The destruction of the completed prototypes and blueprints was carried out by Avro Canada as part of the government's directive.
