Next we have the two Jet Pilots, one female and one male, both of which have identical torsos and helmets. The dark blue torsos, which are unique to this set, are printed with a nice design featuring a red jet with a red, white and gold jet wake plus gold jet insignia on the left breast. The white helmets incorporate a trans-black visor which can be raised and lowered; the helmets feature a print consisting of a star flanked with gold stripes, and like the torsos they’re currently exclusive to this set.
By 1954, Christiansen's son, Godtfred, had become the junior managing director of the Lego Group.[13] 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.[3] In 1958, the modern brick design was developed; it took five years to find the right material for it, ABS (acrylonitrile butadiene styrene) polymer.[11][12] The modern Lego brick design was patented on 28 January 1958.[15]
Primary concept and development work takes place at the Billund headquarters, where the company employs approximately 120 designers. The company also has smaller design offices in the UK, Spain, Germany, and Japan which are tasked with developing products aimed specifically at these markets. The average development period for a new product is around twelve months, split into three stages. The first stage is to identify market trends and developments, including contact by the designers directly with the market; some are stationed in toy shops close to holidays, while others interview children. The second stage is the design and development of the product based upon the results of the first stage. As of September 2008 the design teams use 3D modelling software to generate CAD drawings from initial design sketches. The designs are then prototyped using an in-house stereolithography machine. These prototypes are presented to the entire project team for comment and for testing by parents and children during the "validation" process. Designs may then be altered in accordance with the results from the focus groups. Virtual models of completed Lego products are built concurrently with the writing of the user instructions. Completed CAD models are also used in the wider organisation, for marketing and packaging.[33]
Lego (Danish: [ˈleːɡo];[1][2] stylised as LEGO) is a line of plastic construction toys that are manufactured by The Lego Group, a privately held company based in Billund, Denmark. The company's flagship product, Lego, consists of colourful interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts. Lego pieces can be assembled and connected in many ways to construct objects including vehicles, buildings, and working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects.[3][4]
The design on the jet pilots’ outfits are very good, with a darker blue colour scheme offset with a red/white/yellow stripe pattern on the torso. The requisite wings and plane emblem complete the look, with the star-emblazoned helmet the icing on the cake. However, as good as those outfits are, I think the bi-plane pilots’ attire is even better, with a swish darker red colour on the legs and above the waist, culminating in a flame-effect design merging into a white torso. The old-fashioned flying helmets and goggles look great and really compliment the overall figure design.
In contrast to the first jet with its delta wing configuration and forward canard wings, the second jet features a more conventional straight wing configuration with tapered leading and trailing edges. As you might expect, construction of the fuselage of the second jet is in many ways similar to that of the first, although in order to accommodate twin exhausts the rear isn’t tapered, and the air intakes which flank the fuselage are of a different design.
The main wings are made up of a pair of white 10 x 10 wedge plates with cut corner and no studs in the centre; these are rare, having only previously appeared in two sets in this colour. The red 1 x 1 plate with tooth on each wing tip is also uncommon, having appeared in less than ten sets to date. The sides of the cockpit are made up of stickered red 1 x 4 x 1 panels, and it definitely helps if you concentrate when you apply the stickers, which I clearly didn’t as you can see in the picture below…. The area behind the cockpit canopy is nicely contoured by a red 4 x 4 triple wedge which, I was surprised to discover, has only previously appeared in a single set in this colour. Not to be outdone, however, the large 12 x 2 x 5 tail is appearing for the very first time in red. The hinged trans-black cockpit canopy is yet another rare element, appearing here for only the second time ever; rare it might be, but its pronounced curvature unfortunately means that it somewhat spoils the hitherto sleek lines of the jet. The flipside of this, however, is that the cockpit can comfortably accommodate the pilot.

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.
