Surely somebody has done some work on how many tonnes are going to each different community up north and all those kinds of things, what the cost of bringing that up would be, and what the sell point could be, compared to what it is today with the winter roads, and not being able to bring it year-round. We talked a little bit about just-on-time delivery, all those aspects that will actually enhance the bottom line, not only for the airship company but also for the other companies that they're servicing.
So is there no idea at all, or are we talking five years or twenty years? Do we have any feeling at all on this?
