The major advantage is that you have year-round transport, and you have year-round transport with big bulky things. By pound or by kilo, one of the most expensive things to move to the north is rigid insulation. You can fill a whole truck full of insulation and have half a tonne. The airship's only restriction is weight, and they're so big. So you could have a big cargo bay and you could move big bulky things and awkward pieces. In the north, bringing in something that's pre-assembled reduces your costs a lot. For instance, you cannot bring in pre-formed rafters for houses today. Even the trucks sometimes wouldn't be big enough to bring that in for a community facility. Those are some of the advantages you'd have.
In terms of disadvantages, the only thing we see as a unique characteristic would be if you get caught in a snow and icing condition. Obviously there's a bit of work that needs to be done on how to make sure that the ice doesn't.... It won't affect the flying, but it makes the airship heavy. If it becomes heavy then it might not be able to carry as much freight or it might be forced to the ground. There are ideas on how to come around that. Again, this is part of the technological development that is required. We don't see it as a game stopper, but we can't just ignore it. It's got to be done.
I would also say something that might not be as obvious. We've talked a lot about the north. I think we should also talk about the south. This is a technology. If we can do it in Canada, we can export it around the world. We're not the only place with these kinds of difficult conditions. Certainly with places like the Amazon, the Congo, Siberia, and the outback, there are many places in the world that need this technology. I see this stimulating the aerospace communities in locations like Montreal and Toronto, and I'd hope Winnipeg, so we actually are building machines and selling them. So there's also something in this for the country beyond just serving the north, which we shouldn't completely ignore.
