As far as de Havilland Canada is concerned, they tend to be rather conservative in their work. They innovated in the way of developing aircraft, but in terms of new ideas, revolutionary ideas, because of what they made—bush aircraft, utility airplanes, transport planes—they tended to keep technology rather low.
You should look at companies like Avro Canada. The jetliner was very innovative. You're looking at the second jet airliner in the world. Trans-Canada Airlines was very interested. I wouldn't say invested, but it certainly helped develop the specification. There was research done at the NRC.
Circumstances changed—the Korean war—and TCA got nervous about the airplane also, so they pulled out. By pulling out, it sort of greatly injured the project. In order to sell it, if your national carrier is not interested, it doesn't help. The Korean war put the final nail in the project. If you look at the Avro Arrow, or the CF-100, there was a government need; the air force needed a Canadian airplane developed for Canada's geography. It was developed, it was produced, it proved successful after some bugs, but it proved to be very successful, so government assistance, as far as contracts and research were concerned, proved fruitful.
You need continuity, but circumstances can change. It's extremely fluctuating.
