Construction, Maintenance, and Operation of a Glacial Runway, McMurdo Station, Antarctica

On 7 February 1994, a C-141 departed Christchurch, New Zealand, and landed on the 3050 m (10,000-ft) Pegasus glacial ice runway, located on the Ross Ice Shelf 13 km (8 miles) south of McMurdo, Antarctica. This event marked the final test for a five-year development program to demonstrate the feasibi...

Description
Summary:On 7 February 1994, a C-141 departed Christchurch, New Zealand, and landed on the 3050 m (10,000-ft) Pegasus glacial ice runway, located on the Ross Ice Shelf 13 km (8 miles) south of McMurdo, Antarctica. This event marked the final test for a five-year development program to demonstrate the feasibility of a semipermanent glacial ice runway capable of supporting heavy wheeled aircraft at a site easily accessible to McMurdo. In the later phases of developing the glacial ice runway, numerous working flights of LC-130s operating on wheels (rather than skis) moved cargo more efficiently to the South Pole, and the LC-130 and a C-130 carried larger passenger loads to Christchurch. The primary benefit of the Pegasus runway to the U.S. Antarctic Program is its ability to support heavy wheeled aircraft for most of the period of mid-January through November. In the past, only ski-equipped aircraft could land in the McMurdo area during this time period. The Pegasus runway allows increased payloads for the LC-130 (an additional 3600-kg or 8000-lb takeoff weight when using wheels) and provides access for virtually any conventional aircraft. The technology for siting, constructing, maintaining, and operating such a runway is now well understood and is described in detail in this comprehensive report.
