Catch a ride on some of the world’s biggest and most powerful machines as they try to survive everything Alaska throws at them.

We're targeting heavy-haul trucks that carry 90-ton loads on roads of ice, 100 foot long logging helicopters, massive tugs on the Bering Sea, and the largest non-nuclear ice-breaker in the world - capable of breaking through ice up to 15 feet thick.

We'll look at the technology and engineering that make them work, the incredible challenges they face and the people that keep them running.
