Copenhagen is not only the main airport for the densely-populated Øresund region, but also the main air transportation hub for Scandinavia, the main hub for the joint Danish-Swedish-Norwegian carrier SAS Group, and one of Europe's major hubs. There is a large number of intercontinental connections to Copenhagen, as well as a dense network of short-haul connections from Copenhagen to destinations throughout all of Europe, especially the Nordic countries.
By 1954, Christiansen's son, Godtfred, had become the junior managing director of the Lego Group. It was his conversation with an overseas buyer that led to the idea of a toy system. Godtfred saw the immense potential in Lego bricks to become a system for creative play, but the bricks still had some problems from a technical standpoint: their locking ability was limited and they were not versatile. In 1958, the modern brick design was developed; it took five years to find the right material for it, ABS (acrylonitrile butadiene styrene) polymer. The modern Lego brick design was patented on 28 January 1958.
The railway station, 1 Københavns Lufthavn, Kastrup Station (sometimes called CPH Airport Station and wrongly Kastrup Station), is located in Terminal 3. The station has frequent connections to Copenhagen and Malmö, as well as InterCity trains for the rest of Denmark and a few daily SJ 2000 express trains for Stockholm. The frequent Øresund trains between Copenhagen and Malmö continue in Denmark to Elsinore and in Sweden to a number of destinations in Scania and other parts of Götaland. The travel time to Copenhagen Central Station is 12 minutes, and 20 minutes to Malmö Central Station.
Apart from that, both carriers have extensive networks within Europe and the Mediterranean (including North Africa and the Middle East). SAS flies to most European capitals, and has a particularly dense network of connections across the Baltic Sea, to Finland, Estonia, Latvia and Lithuania, as well as to Poland, where it serves the majority of even small airports. There is also a fairly good network of connections to the United Kingdom and, perhaps surprisingly, to Italy, where even smaller airports like Bologna are served.
The final two minifigures are the Biplane Pilot and the intrepid Wing Walker. Both of these minifigures share the same white torso which is printed with a flight suit design overlaid with dark red and bright light orange flames plus a logo over the left breast. The torso design is superb and it can at present only be found in this set. Both minifigures are provided with a reddish brown aviator cap and dark bluish grey goggles, and the pilot (below left) also gets an alternative to this headgear in the form of medium dark flesh mid-length hair which has only ever appeared in five sets in this colour.
