The Ice Runway( ICAO : NZIR) is the principal runway for the U.S. Antarctic Program during the summer Antarctic field season due to its proximity to McMurdo Station. The other 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 is 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 C17 cargo space. [3]

The annual sea-ice runway for wheeled aircraft is constructed at the start of each season and is used until early December when the sea ice begins to break up. [4] Subsequently flight operations are moved back to Williams Field. Pilots landing C-17 Globemaster III cargo aircraft on the sea ice runway report that the surface is stable, not unlike landing on concrete. The similarity with land bases ends when the jet aircraft rolls to a stop, however. The nearly 450,000 pound (= 201 tons) weight of the plane, including cargo and passengers, causes it to sink into the ice, albeit only a matter of inches. A laser light is trained on the aircraft to measure the settlement rate. The $200 million aircraft is moved to a new location on the six-foot-thick ice as a safety measure if the 10-inch red line is reached, according to the News Tribune in Tacoma, Washington.[ citation needed ]

Accidents and incidents

On 31 October 1960, a United States Navy Lockheed EC-121 Warning Star from Oceanographic Development Squadron Eight crashed while attempting to land on the Ice Runway. The pilot and co-pilot were badly injured, but the other crew received minor injuries or were uninjured. The aircraft was not recovered, and was simply allowed to sink when the ice melted in the spring. [5] [6]

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.

Eastern Air Lines, also colloquially known as Eastern, was a major American airline from 1926 to 1991. Before its dissolution, it was headquartered at Miami International Airport in an unincorporated area of Miami-Dade County, Florida.

Williams Field Airstrip in Antarctica

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.

Piarco International Airport

Piarco International Airport is an international airport serving the island of Trinidad and is one of two international airports in Trinidad and Tobago. The airport is located 30 km (19 mi) east of Downtown Port of Spain, located in the adjacent town of Piarco.

The airport is also the primary hub and operating base for the country's national airline, as well as the Caribbean's largest airline, Caribbean Airlines.

Pegasus Field

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 expected to start in February 2017.

Shellharbour Airport Airport serving the Illawarra region and Wollongong, Australia
