Blue ice runway
A blue ice runway is a runway constructed in Antarctic areas with no net annual snow accumulation. The density of the ice increases as air bubbles are forced out, strengthening the resultant ice surface so that aircraft landings using wheels instead of skis can be supported. Such runways simplify the transfer of materials to research stations, since wheeled aircraft can carry much heavier loads than ski-equipped aircraft.[1]
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. The United States Antarctic Program uses them to support its substantial science activities.
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.
