Just before 10 a. The television cameras captured models undergoing spin and "free flight" tests, a wooden engineering mock-up, engineers subjecting the various components of the plane to arduous tests, and test pilots checking out the cockpit.
But the dream of producing the plane that would bring Canadian aviation into the supersonic age was ended in On Feb. Prime Minister John Diefenbaker explained the reasoning behind the unequivocal scrapping of the project. With the current development in the U. Binnie, who helped the team on conservation issues, said getting the DTV out of the water posed a lot of challenges, mostly coming from how little was known about the object.
Removing a decades-old historical artifact from its sunken resting place could possibly break it into pieces.
The DTV was covered in layers and layers of quagga mussels, which had used threads of protein to stick to the surface of the test vehicle. Prying them off, Binnie said, could risk destroying the paint and losing key information about the model.
It was really considered important. The team had set out to find one of the final five test models, which were almost identical replicas of the completed Avro Arrows. Three years after they found the DTV, in mid-September , they finally made headway. The only problem was that it was in pieces. He says the team is still trying to determine how to remove the piece, and are planning on reviewing their existing sonar images nearby.
But for now, the four-year search for the Avro Arrow test models is coming to a close. You can see an image of them and it takes us back to that moment where Canada was punching well above its weight.

For many Canadians, the Avro Arrow has come to symbolize both the potential, and the unfulfilled promise, of Canadian innovation. But the cancellation of the Arrow absolutely devastated the Canadian aerospace industry. When it comes to the Avro Arrow, the true regret is what might have been: Flying saucers.
Hover cars. A Lunar rover — and even the possibility of a Canadian using it. The reasons for the cancellation of the Arrow were a mix of politics, timing, and bad luck. The CF as the Arrow was officially known was originally designed as a long-range interceptor, meant to meet and destroy Soviet bombers.
But on October 4, — the same day as the first Avro Arrow rolled off the production line — the Soviets launched the satellite Sputnik, becoming the first nation to put a man-made object into orbit. That development changed the focus for militaries on both sides of the Cold War, away from conventional bombers and towards atmospheric weapons like intercontinental ballistic missiles. They were complete polar opposites.
One of the specifics of this deal was the purchase by the U. Air Force of the new Avro Arrow fighter. Even Americans were shocked, because they expected some pushback.
It had to be to operate in the harsh conditions of the Arctic and be able to fly the long distances that this required. To achieve these goals, the Avro engineers created the first non-experimental fly-by-wire control system a system that replaces the conventional manual flight controls of an aircraft with a computer-controlled system in an aircraft and a navigational computer that used real-time telemetry.
They used new materials in its airframe, and, at a sister company, designed and built the new powerful, lightweight, supersonic Iroquois engine.
To make the most of its capabilities, the interceptor spawned a new weapons programme called Astra nicknamed "Astronomically Expensive" , and a new missile.
The Arrow was so advanced that Canada didn't have all the facilities for testing it. The Canadians and their aircraft impressed their American colleagues — a calling card that had lasting consequences for the future of humanity.
The Arrow achieved another first. It was the first time that engineers built prototypes of such a sophisticated aircraft using production tooling rather than handmade by engineers. This process meant that it was a mere 28 months from the first drawing of the Arrow to its rollout, and by February the production line was up and running.
By the time the loudspeaker crackled into life on Black Friday, there were five flying prototypes. There was another fitted with an Iroquois engine nearly ready to fly and another four in various states of assembly.
In the factory were the majority of parts for the production aircraft. Proposals for a Mach 3 and a hypersonic — Mach 5 — version of the Arrow were on the drawing board, as was a "zero-length launch Arrow", which would blast into the air from a raised launch pad like Thunderbird 1 from the science fiction television series.
The government had cancelled the Astra system already. One Iroquois engine was given to Britain to help its supersonic airliner project. Yet, the government didn't pursue the project, despite commercial interest.
The 32 men they chose went to work on projects like Mercury, Gemini and Apollo. Owen Maynard, a former senior stress engineer, was the man most responsible for the design of the Lunar Module.
