If you look globally at the aerospace industry, you see that because of the kind of R and D that's required, with the long timelines, the high risk, the long payback periods, and the high value of the kinds of technologies that are being created, governments around the world are investing in R and D in this particular field.
The Canadian government has had some version of the SADI program since 1959, with DIPP and technology partnerships Canada, then SADI. I think that's really a function of this industry, and the fact that it is such a high tech, innovation intensive industry but also high risk.
It would not be for me to decide what would happen in the future, but certainly past and international experience suggest that in this area innovation has significant economic payback, both to the society and also to the specific industry.
