The programmable Lego brick which is at the heart of these robotics sets has undergone several updates and redesigns, with the latest being called the 'EV3' brick, being sold under the name of Lego Mindstorms EV3. The set includes sensors that detect touch, light, sound and ultrasonic waves, with several others being sold separately, including an RFID reader.[52]
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]
Colour-wise, it is mainly yellow, with only a dash of green and red, and a little more white, there to break it up. The worker has space to stand and drive the vehicle, and has a walkie talkie attached on the side of the car. Around the other side is a coiled-up, what I assume is a, fuel pump. It looks pretty good when coiled up on the side of the car. Stickers come into use again here, this time for the number plates.
The construction of the new airport was carried out during 1964 and the airport opened on 1 November, with one runway at 1660 meters in length and 45 meters width, a small platform where aircraft could be served, and a control tower to the controller. Hans Erik Christensen, the former chief pilot at LEGO became director, and the passengers were handled in LEGO's hangar until the first terminal building was opened in the spring of 1966. The airport was continuously expanded the following years, with new facilities, terminal buildings, lounge, tax-free area and hangars where LC Johansen's studio often participated as an architect (today called the Johannsen Architects), while other work was carried out by the airport's own studio.

City is the thematic title under which most Town-related System sets were released from 2005 and onward. There are numerous sets that are associated with Construction, Police, Fire, Emergency, Train, Airport, Transportation, Cargo, Traffic, Coast Guard, Farm, Great Vehicles, Mining, and Space. European catalogs featured another theme called City in the years 1999 to 2000, which was referred to as City Center in American catalogs.

The rest of the model is pretty standard for a Marvel release. Most of the larger sets revolve around a vehicle and/or small structure. This one doesn’t disappoint in that respect. First up, you get the airport control tower. It’s fairly uninteresting, although they have added an exploding wall-play feature which kinda makes up for it. Otherwise, though, it’s simply a tower. In addition to that you get a small baggage car, which is pretty neat. In fairness, as cute as it is, it feels like an attempt to bump up the number of pieces. Lastly, the set comes with a Quinjet. This particular vehicle is considerably smaller than the previous two minifigure-scale Quinjets that Lego gave us last year and in 2012. That said, it’s a great model with some great features.
The remainder of the build is the control tower and terminal building. First there is a metal detector screener leading to the waiting/secure area of the airport, which seems taller than it needs to be for the minifigures. I think the same effect could have been made with half the height, except that would not allow for an impressive height for the overall tower. However it does seem to be similar to many modern airports with the high ceilings. This area also seems to be someplace to check luggage as evidenced by the rather nifty conveyor belt that comes in a full part. The moving parts of the set include a revolving door (a very tall one, for the first floor) that leads from the secure area of the airport out to the tarmac, and of course the conveyor belt.
