Every year, up to six million tons of snow fall at Ted Stevens International Airport (ANC) in winter, and this season, there are no signs of the bad weather letting up. The airfield clearing team has been working 24/7 to keep the runways open during a storm that would shut down other airports in minutes. Witness the precisely choreographed dance of multi-million-dollar machinery used to plow potentially lethal ice and snow and to clear the 6,000 lights and high tech instrument landing systems so pilots can safely land their planes.
