Yes, as Canadian, Avro Arrow does leave a "What if..." thought in my mind but having said that, I am proud of my countrymen as we have achieved quiet a lot since then (given our tiny population and difficult logistics):

Canada Space Arm, Blackberry (RIM), Bombardier aircrafts/subways/streetcars/trains, de Havilland aircrafts as well as other aircrafts (https://en.wikipedia.org/wiki/List_of_aircraft_of_Canada%27s...).

As to why was Avro Arrow scrapped - sure there are explanations and the leading ones tend to indicate external political pressure coming from USA but I am not bitter at the reasons behind it because it is one thing to be cross at the decision but I don't have any clear idea as to actual reasons and the thought process of our leaders at the time.

It was scrapped because it was doomed to be a bad fighter plane. Speed isn’t everything. The Vigilante, Delta Dart, etc all were expensive failures because you need a lot more than speed.

Let’s not be too proud of Bombardier, eh?
