Good morning! I didn’t have a theme reveal, but I decided – since I’m a Canadian living in Colorado – that I am going to focus my #AtoZChallenge on Canadiana. Words, phrases, things, foods, places. This should be interesting. Believe it or not, I’ve had a hard time coming up with topics for every letter of the alphabet: I think mostly because I take those things for granted.
So, today I’d like to talk about the CF-105 Avro Arrow! This is a little different than my usual kayaking and adventure posts, but I hope you’ll find it interesting…
The CF-105 Avro Arrow made its first test flight almost exactly 58 years ago (March 25, 1958). It was supposed to be a state-of-the art Canadian designed (and made) delta-wing, hypersonic interceptor, intended to fly at Mach 2 speeds over 50,000 feet. This aircraft was going to put Canada on the aviation map.

But it didn’t quite happen that way and has gone down in history as a legend, a conspiracy story, a failure.
In February of 1959, the entire project was cancelled and within two months, there was very little evidence that the aircraft ever existed.

This is where things started getting interesting. There were so many theories abound: one that a Russian spy had infiltrated the production line; many political theories; and rumours that one Avro Arrow was hidden from destruction, to name a few.
Only five years ago, information surfaced suggesting that an ejection seat from a CF-105 was found in the United Kingdom, owned by a private collector, refuelling speculation about the possibility that a complete jet was saved from destruction and possibly flown across the Atlantic. The owner of the seat told CTV News that he was “100% positive” he saw an Arrow land at RAF Manston Air Base when he was a teen, living near the base.
The Avro Arrow will go down in history as a Canadian legend, and unsolved mystery and to many a missed opportunity to make aviation history.
While the Arrow was capable of supersonic flight, the term hypersonic generally refers to speeds of Mach 5 and above. The Arrow is an interesting story that highlights what Canada is capable of…
The term hypersonic was used for speeds of Mach 5 and above from the 1970’s onward. In 1958, Mach 2 was considered hypersonic. It’s a shame the program was scrapped the way it was. Most of the engineers who worked on the Arrow all left to work for NASA’s Space Task Group – possibly the beginning of Canada’s “brain drain”?
RCAF Operational Requirement OR 1/1-63 was for “Supersonic All-Weather Interceptor Aircraft”, as were the follow up reqs. I think the Arrow was simply too much of an offensive-capable system for peace keeping Canada…
