A permanent, hard-ice runway for wheeled planes — the Pegasus White Ice Runway was completed in 1992. The runway is located about 30 kilometers (19 miles) from McMurdo on the glacial ice of the McMurdo Ice Shelf and has a thin compacted "white ice" pavement that can support wheeled aircraft from throughout the austral summer, except during the warmest months.

Williams Field, a skiway 15 kilometers (9 miles) from McMurdo on the Ross Ice Shelf, is the aerodrome for ski-equipped airplanes. Wheeled airplanes use a harder, smoother runway on sea ice in October and November and into December, when the sea ice usually begins to break up and become unusable, or the white-ice runway Pegasus on the McMurdo Ice Shelf.
