Pegasus Field is an airstrip in Antarctica, the southernmost of three airfields serving McMurdo Station. Pegasus is a blue ice runway capable of handling wheeled aircraft year-round, and the principal Ice Runway on the sea-ice available during the summer Antarctic field season. The other two are the snow runways at Williams Field that are limited to ski-equipped aircraft. The field is named after Pegasus, a C-121 Lockheed Constellation, still visible there in the snow after crashing in bad weather on October 8, 1970. No one on board was injured.
