Ice Airport Alaska

Father-son aviators battle turbulence to refuel a remote mine, bush pilots fight an aerial jam to reach Alaska's biggest sled race, and the Coastguard turn a C-130 into a bomber to drop supplies on an isolated beach.

Fish and Wildlife aviators battle Arctic conditions to track down a polar bear population, a bush pilot races fading daylight to save a business, Anchorage field crews battle to clear an icy runway, and CBP officers investigate.

Pilots fly over the dangerous Brooks mountains, so engineers can fix a remote weather station, a veteran pilot tests a rookie on their bush plane landings, crews fight ice and wind to save a winter festival, and engineers race.
