The main constituents of the set are a tanker truck, three aircraft and a hangar. Each of these gets its own instruction booklet and bags of elements. First up is the tanker truck (below) which at only four studs wide and less than ten studs in length reminds me of the 4-stud wide vehicles of my youth. This impression is reinforced by the inclusion of a couple of late 70’s-style 2 x 4 mudguards in the build.
Billund Airport had its beginning in 1961 when the son of the founder of the Lego Group, Godtfred Kirk Christiansen, established a private 800-meter long runway and hangar north of his factory in Billund. With Christiansen as a key driver, more of the neighbouring municipalities were included in the group of owners, and it was planned that the airport should be expanded to a regular public airport.
The definitive shape of the Lego bricks, with the inner tubes, was patented by the Lego Group in 1958. Several competitors have attempted to take advantage of Lego's popularity by producing blocks of similar dimensions, and advertising them as being compatible with Lego bricks. In 2002, Lego sued the CoCo Toy Company in Beijing for copyright infringement over its "Coko bricks" product. CoCo was ordered to cease manufacture of the products, publish a formal apology and pay damages. Lego sued the English company Best-Lock Construction Toys in German courts in 2004 and 2009; the Federal Patent Court of Germany denied Lego trademark protection for the shape of its bricks for the latter case. In 2005, the Lego Company sued Canadian company Mega Bloks for trademark violation, but the Supreme Court of Canada upheld Mega Bloks' rights to sell their product. In 2010, the European Court of Justice ruled that the eight-peg design of the original Lego brick "merely performs a technical function [and] cannot be registered as a trademark."
