Right. Let me deal first of all with the question of weather, because in Canada we always like to talk about the weather—we have a lot of it.
We have a very fierce winter, and the airships that exist today are basically fair-weather flyers, so they would fly in summer, spring, and fall. It doesn't mean they cannot fly in the winter. In fact, the very first vehicle to cross the North Pole was an airship. The Italian airship Norge flew there.
However, there has been no demand for advertising blimps or surveillance blimps in the north, so now the companies have designed their airships to live in 20 degrees or 30 degrees below centigrade, which is what we have to deal with. It can be done.
