The very day thatJohn George Diefenbaker  ordered the break up of the Arrows was the day that famous test pilot Jan Zurakowski was to fly an Arrow over the lake in front of the CNE stands to watch the airshow. This writer was there, waiting, with his dad, and we were severely disappointed because the Arrow never came. 

Dief had been shocked at the costs and what the reaction of the Americans was to the very idea of buying the Arrow from Canada, the very market that Avro hadn't addressed. He could have allowed production to equip the RCAF and not have to buy from the Yanks, and he didn't do that, possibly ending up with more costs for their (possibly inferior) planes than if he had approved production for the RCAF under the defense budget.  We will never know. His decision helped put the Liberals back in charge.

The Avro and Orenda engineers and scientists then went south to help out the US aircraft and space industries.
