The Annual Sea-Ice Runway( ICAO : NZIR) [3] was the principal runway for the U.S. Antarctic Program during the summer Antarctic field season due to its proximity to McMurdo Station, until 2017. The present two runways in the area are the snow runway at Williams Field (NZWD) and the compacted snow runway at Phoenix Airfield (NZFX), which replaced Pegasus Field (NZPG) in 2017.
The sea ice runway was capable of handling wheeled aircraft, which have included to date: Lockheed C-5 Galaxy, Lockheed C-141 Starlifter, Boeing C-17 Globemaster III, Lockheed C-130 Hercules and Lockheed P-3 Orion. In the summer season of 2009/2010 the RNZAF trialed a modified Boeing 757 operationally. The intention is to use the Boeing 757 for passenger transport, thereby freeing up capacity for C-17 cargo space. [4]
The annual sea-ice runway for wheeled aircraft was constructed at the start of each season and used until early December when the sea ice began to break up. [5] Subsequently flight operations were moved back to Williams Field. Pilots landing C-17 Globemaster III cargo aircraft on the sea ice runway reported that the surface was stable, not unlike landing on concrete. The similarity with land bases ended when the jet aircraft rolled to a stop, however. The nearly 450,000 pound (= 201 tons) weight of the plane, including cargo and passengers, caused it to sink into the ice, albeit only a matter of inches. A laser light was trained on the aircraft to measure the settlement rate. The $200 million aircraft was moved to a new location on the six-foot-thick ice as a safety measure if the 10-inch red line was reached, according to the News Tribune in Tacoma, Washington.[ citation needed ]
Whilst no formal records have been located of a permanent decommissioning of the McMurdo sea-ice runway, interest in eliminating its use began with the development of Pegasus Field in 1992. [6] Concept studies were commenced into the possibility of downscaling from three McMurdo airports to two or one, leading to Pegasus being trialled as a replacement for the sea-ice runway at the start of the annual summer season in 2008-09 [7] . Based on the results of this work proving that Pegasus Field was unsuitable for use during the warmer part of the summer due to excessive snow melt, the development of Phoenix Airfield was commenced in 2014 with the intention of it being capable of operating for wheeled aircraft throughout the entire summer, thus proving the single airport concept. [8] Following the 2017 opening of Phoenix Field, all references to the sea-ice runway were removed from the USAP website [9] and official documentation. [10]
The sea-ice runway site is still shown in flight tracking [11] [12] and airport information [1] [2] websites, leaving unresolved the question of its current official status. However, it has never been a fixed permanent location in any of its years of operation because of the annual melting of the ice in McMurdo Sound during the Antarctic summer.
Transport in Antarctica has transformed from explorers crossing the isolated remote area of Antarctica by foot to a more open era due to human technologies enabling more convenient and faster transport, predominantly by air and water, but also by land as well. Transportation technologies on a remote area like Antarctica need to be able to deal with extremely low temperatures and continuous winds to ensure the travelers' safety. Due to the fragility of the Antarctic environment, only a limited amount of transport movements can take place and sustainable transportation technologies have to be used to reduce the ecological footprint. The infrastructure of land, water and air transport needs to be safe and sustainable. Currently thousands of tourists and hundreds of scientists a year depend on the Antarctic transportation system.
The McDonnell Douglas/Boeing C-17 Globemaster III is a large military transport aircraft developed for the United States Air Force (USAF) between the 1980s to the early 1990s by McDonnell Douglas. The C-17 carries forward the name of two previous piston-engined military cargo aircraft, the Douglas C-74 Globemaster and the Douglas C-124 Globemaster II.
McMurdo Station is an American Antarctic research station on the southern tip of Ross Island, which is in the New Zealand–claimed Ross Dependency on the shore of McMurdo Sound in Antarctica. It is operated by the United States through the United States Antarctic Program (USAP), a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,500 residents, and serves as one of three year-round United States Antarctic science facilities. All personnel and cargo going to or coming from Amundsen–Scott South Pole Station first pass through McMurdo. McMurdo Station continues to operate as the hub for American activities on the Antarctic continent. By road, McMurdo is 3 kilometres (1.9 mi) from New Zealand's smaller Scott Base.
The Lockheed P-2 Neptune is a maritime patrol and anti-submarine warfare (ASW) aircraft. It was developed for the US Navy by Lockheed to replace the Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion. Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched, stop-gap nuclear bombers that would have to land on shore or ditch. The type was successful in export, and saw service with several armed forces.
Peter O. Knight Airport is an airport on Davis Islands, five minutes from downtown Tampa, Florida. Built as a Works Progress Administration project, it was Tampa's main airport from 1935 to 1945, and is still used by general aviation operators today because of its proximity to the central city. The airport was named for prominent attorney and businessman Peter O. Knight, namesake of Holland & Knight.
The Lockheed LC-130 is a ski-equipped United States Air Force variant of the C-130 Hercules used in the Arctic and Antarctic. Ten are currently in service with the 109th Airlift Wing of the New York Air National Guard.
The United States Antarctic Program is an organization of the United States government which has a presence in the Antarctica continent. Founded in 1959, the USAP manages all U.S. scientific research and related logistics in Antarctica as well as aboard ships in the Southern Ocean.
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.
Johan Adolf Pengel International Airport, also known as Paramaribo-Zanderij International Airport, and locally referred to simply as JAP, is an airport located in the town of Zanderij and hub for airline carrier Surinam Airways, 45 kilometres (28 mi) south of Paramaribo. It is the larger of Suriname's two international airports, the other being Zorg en Hoop with scheduled flights to Guyana, and is operated by Airport Management, Ltd./ NV Luchthavenbeheer.
Williams Field or Willy Field is a United States Antarctic Program airfield in Antarctica. Williams Field consists of two snow runways located on approximately 8 meters (25 ft) of compacted snow, lying on top of 8–10 ft of ice, floating over 550 meters (1,800 ft) of water. The airport, which is approximately seven miles from Ross Island, serves McMurdo Station and New Zealand's Scott Base. Until the 2009–10 summer season, Williams was the major airfield for on-continent aircraft operations in Antarctica.
Pegasus Field was an airstrip in Antarctica, the southernmost of three airfields serving McMurdo Station. It closed due to excessive melting in the summer season caused by warmer temperatures combined with dust and dirt blown in from nearby Black Island. The last flight was on December 8, 2016 and it was replaced by Phoenix Airfield with flights starting in February 2017.
Troll Airfield is an airstrip located 6.8 kilometres (4.2 mi) from the research station Troll in Princess Martha Coast in Queen Maud Land, Antarctica. Owned and operated by the Norwegian Polar Institute, it consists of a 3,300-by-100-metre runway on glacial blue ice on the Antarctic ice sheet. The airport is located at 1,232 metres (4,042 ft) above mean sea level and is 235 kilometres (146 mi) from the coast.
Shellharbour Airport, formerly Illawarra Regional Airport, also referred as Albion Park Aerodrome or Wollongong Airport, is an airport located in Albion Park Rail, New South Wales, Australia.
Patriot Hills Base Camp was a private seasonally occupied camp in Antarctica. It was located in the Heritage Range of the Ellsworth Mountains, next to the Patriot Hills that gave it its name.
Hudman Glacier is a glacier draining south of Mount Landolt between Marze Peak and Miller Peak in Petvar Heights at the south end of the Sentinel Range, in the Ellsworth Mountains of Antarctica, flowing south-southeast to Minnesota Glacier. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1957–59, and was named by the Advisory Committee on Antarctic Names for Captain Rayburn A. Hudman, United States Marine Corps, who died in the crash of a Lockheed P2V-2n Neptune, modified for extreme range, flying in sub zero temperatures and Ski equipped for landing on the Ice runways at McMurdo Sound Antarctica on October 18, 1956.
Antarctic Development Squadron Six was a United States Navy air test and evaluation squadron based at Naval Air Station Point Mugu, California with forward operating bases at Christchurch, New Zealand and McMurdo Station, Antarctica.
The Historical Aircraft Restoration Society, often referred to by its acronym, HARS, is an Australian based aircraft restoration group. The group has two museums, at Shellharbour Airport in New South Wales, Australia, and Parkes, New South Wales, Australia. HARS was formed in 1979 by a group of aviation enthusiasts interested in the preservation of Australian Aviation History. Its mission is "To recover and where possible restore to flying condition, aircraft or types of aircraft that have played a significant part in Australian Aviation History both in the Civil and Military arenas".
Pegasus Road is an 18-mile (29 km) long road of dirt and packed snow constructed by the United States Antarctic Program on Ross Island and the Ross Ice Shelf in Antarctica. The trip along the road from McMurdo Station to Pegasus Field takes approximately 45 minutes in a "Delta" wheeled vehicle, although on occasion high temperatures have damaged the runway and caused the road surface to deteriorate enough to lengthen the trip to two hours.
Phoenix Airfield is an airstrip in Antarctica opened in early 2017, designed to replace the Pegasus Field's role in serving McMurdo Station.
