With the challenges of the warmer winters and the challenges they're having with winter roads to do exploration and mine development, could there be more use of airlift and more airports in the area rather than looking at land transportation? That way, it actually has less impact on the environment. Maybe it would be cheaper in the long run.
Also, as we heard from the transportation ministry, there's a desire to have more air patrols around the Arctic to have a presence and to protect our sovereignty of that area.
