A blue ice runway is a runway constructed in Antarctic areas with no net annual snow accumulation, so that the resultant ice surface is capable of supporting aircraft landings using wheels instead of skis. They are intended to make transferring materials to research stations simpler, since wheeled aircraft can carry much heavier loads than ski-equipped aircraft.
Blue ice runways are created as a way of streamlining transport to the interior. Without them, most heavy materials must be brought by ship, then ferried inland by ski-equipped smaller aircraft. Large, wheeled aircraft can fly directly into the interior, saving time and money. In particular, they allow for rare medical evacuations to take place year round.
Because of ice's low coefficient of friction, planes tend to decelerate with reverse thrust, as opposed to traditional means of braking the wheels, and so runways are often several miles long.
Famous quotes containing the words blue and/or ice:
“That air would disappear from the whole earth in time, perhaps; but long after his day. He did not know just when it had become so necessary to him, but he had come back to die in exile for the sake of it. Something soft and wild and free, something that whispered to the ear on the pillow, lightened the heart, softly, softly picked the lock, slid the bolts, and released the prisoned spirit of man into the wind, into the blue and gold, into the morning, into the morning!”
—Willa Cather (1873–1947)
““The room’s very hot, with all this crowd,” the Professor said to Sylvie. “I wonder why they don’t put some lumps of ice in the grate? You fill it with lumps of coal in the winter, you know, and you sit round it and enjoy the warmth. How jolly it would be to fill it now with lumps of ice, and sit round it and enjoy the coolth!””
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
