The Lego Group began in the workshop of Ole Kirk Christiansen (1891–1958), a carpenter from Billund, Denmark, who began making wooden toys in 1932.[7][8] In 1934, his company came to be called "Lego", derived from the Danish phrase leg godt, which means "play well". In 1947, Lego expanded to begin producing plastic toys.[9] In 1949 Lego began producing, among other new products, an early version of the now familiar interlocking bricks, calling them "Automatic Binding Bricks". These bricks were based on the Kiddicraft Self-Locking Bricks, which had been patented in the United Kingdom in 1939[10] and released in 1947. Lego had received a sample of the Kiddicraft bricks from the supplier of an injection-molding machine that it purchased.[11] The bricks, originally manufactured from cellulose acetate,[12] were a development of the traditional stackable wooden blocks of the time.[9]
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.
Lego pieces of all varieties constitute a universal system. Despite variation in the design and the purposes of individual pieces over the years, each piece remains compatible in some way with existing pieces. Lego bricks from 1958 still interlock with those made in the current time, and Lego sets for young children are compatible with those made for teenagers. Six bricks of 2 × 4 studs[28] can be combined in 915,103,765 ways.[29]
As is the norm with LEGO sets these days, there are a fair few stickers in use for this item. I’m still not a fan of their use, but at this point in time, it is something I have come to expect and just get on with it now. In their defence, they do add to the overall presentation, making it that little bit harder to complain. As I said, this is my favourite of the three planes in the set, mainly because it looks superb and offers a great build experience. Seriously, I had so much fun building this. The instructions – as always – are clear, and it is not going to provide any major issues. Stability-wise, there are no concerns here, with the finished product very sturdy and, as proved by my daughter, can handle itself when being flown around the room by an excited seven-year-old. One minifigure can be seated at the controls, with suitable space for application and removal. The other pilot has its place on the top of the plane, with a single piece of black fencing to provide support for the death-defying pilot.
The middle section of the terminal (between the B and C gate areas) are dedicated to high-end fashion and accessories, among others you will find Gucci, Burberry and BOSS stores there. Other types of stores — many of which have two outlets, one east and one west of this section — include FineFood (domestic and international delicacies from fine cheese to foie gras and craft beer), WHSmith (books), Scandinavian Souvenirs (self-explanatory), and last but not least the five Heinemann Tax Free stores.

In December 2012, the BBC's More or Less radio program asked the Open University's engineering department to determine "how many Lego bricks, stacked one on top of the other, it would take for the weight to destroy the bottom brick?"[44] Using a hydraulic testing machine, the engineering department determined the average maximum force a 2×2 Lego brick can stand is 4,240 newtons; since an average 2×2 Lego brick has a mass of 1.152 grams (0.0406 oz), according to their calculations it would take a stack of 375,000 bricks to cause the bottom brick to collapse, which represents a stack 3,591 metres (11,781 ft) in height.[44]

Agent 13 has a pretty plain appearance, with caramel-coloured wavy hair, and a black, spy-like top. Her torso has some nice details, with sharp, angular lines that all combine to form a rough outline of an upside down star. She has plain sand blue pants and rocks a sub-machine gun accessory. I like regular LEGO firearms, so it’s very nice to get one in this set as they’re fairly uncommon.
