Polar Path Scandinavian: SAS, A Scandinavian Air League with a Polar Path Scandinavian Airlines em, a network not only of the north but of all Europe, and now, with its ; to Tokyo, Argentina-Chile and Johannesburg, a five-continent "big fellow," been a maker of air history from its primitive start in 1919, when Denmark,then the other Scandinavian lands, formed individual air lines that have 3 been merged.
Big history was made late in 1952, when SAS flew its first test flights of mercial planes from Los Angeles to Copenhagen by the Polar Route.
To navigate this path SAS used the Arild Viking, first polar plane of ac-:able design, being a modified Douglas DC6B, fixed up as a sleeper plane i berths and so-called "dormette" seats. To overcome compass confusion in polar zone, where ordinary compasses get the willies and are useless, a new dix gyrocompass and other complex "thinking gadgets" were used.
This revolutionary polar route, opening on a year-round basis, with Los ;eles as the American terminus, was officially agreed to in the spring of 1954 lie U.S. State Department and the Civil Aeronautics Board on a three-year s, to become permanent when the route proves economically sound. Semi-:kly first-class service started late in '54 and will be followed by tourist service.
The range of climates can be broadly grouped under three headings, according to latitude. Tropical climates are hot and dominated by equatorial air masses throughout the year. Temperate climates of the mid-latitude zone are variable, dominated alternately by subtropical and sub-polar air masses, and usually seasonal. Polar climates of high latitudes are uniformly cold, under the continuous control of sub-polar and polar air masses and strongly seasonal. |
