The transportation system in Greenland is very unusual in that Greenland has no railways, no inland waterways, and virtually no roads between towns. Historically the major means of transportation has been by boat around the coast in summer and by dog sled in winter, particularly in the north and east. Nowadays air travel, by helicopter or other aircraft, is the main way of travel.

Bluie West One, later known as Narsarsuaq Air Base and Narsarsuaq Airport, was built on a glacial moraine at what is now the village of Narsarsuaq, near the southern tip of Greenland. Construction by the United States Army began in June 1941. The first aircraft landed there in January 1942, as a link in the North Atlantic air ferry route in World War II. The base had a peak population of about 4,000 American servicemen, and it is estimated that some 10,000 aircraft landed there en route to the war in Europe and North Africa.
