Desc: Man Made: Alaska's Extreme Machines: Directed by David Huntley. With Roger Tilling. It's said that Alaska in winter isn't fit for man nor beast. But for Alaska's Extreme Machines, when there's a job to do there's no backing down, because taking on extreme conditions on the Final Frontier is just what they're made for. This is the story of three massive and magnificent machines specially designed and built to take on and survive whatever Alaska throws at them: the most powerful ocean tug in the country, built to tow huge loads and withstand winter crossings of the storm-tossed Gulf of Alaska; a massive self-propelled mobile oil drill rig, built to endure the brutal arctic conditions on Alaska's North Slope; and the biggest, toughest ship in the U.S. fishing fleet, a floating city and fish factory rolled into one, designed to stay out on the rough Bering Sea for up to a month at a time. It's tough men and their monster machines versus Alaska's extreme conditions.
