Since 1963, Lego pieces have been manufactured from a strong, resilient plastic known as acrylonitrile butadiene styrene (ABS).[12][30] As of September 2008, Lego engineers use the NX CAD/CAM/CAE PLM software suite to model the elements. The software allows the parts to be optimised by way of mould flow and stress analysis. Prototype moulds are sometimes built before the design is committed to mass production. The ABS plastic is heated to 232 °C (450 °F) until it reaches a dough-like consistency. It is then injected into the moulds at pressures between 25 and 150 tonnes, and takes approximately 15 seconds to cool. The moulds are permitted a tolerance of up to twenty micrometres, to ensure the bricks remain connected.[33] Human inspectors check the output of the moulds, to eliminate significant variations in colour or thickness. According to the Lego Group, about eighteen bricks out of every million fail to meet the standard required.[37] Lego factories recycle all but about 1 percent of their plastic waste from the manufacturing process. If the plastic cannot be re-used in Lego bricks, it is processed and sold on to industries that can make use of it.[38][39] Lego has a self-imposed 2030 deadline to find a more eco-friendly alternative to the ABS plastic it currently uses in its bricks.[40]

Other than the planes, I do find it unfortunate that the Friends set focuses on shopping and food like so many Friends sets, and I also think it is unfortunate that the City terminal only has the basics of the airport structure in the control tower and service truck. Having a control tower for the Friends set would have been great. Having a gift shop/cafe for the City terminal would have been a worthwhile addition and not something we have seen in many City sets.
After Lego closed down their publishing subsidiary, they moved on to a partnership with Traveller's Tales, and went on to make games like Lego Star Wars, Lego Indiana Jones, Lego Batman, and many more including the very well-received Lego Marvel Super Heroes game, featuring New York City as the overworld and including Marvel characters from the Avengers, the Fantastic Four, the X-Men, and more.[74][75] More recently, Lego has created a game based on The Lego Movie, due to its popularity.[76]
Anyway, I think this may be my favorite LEGO City air terminal yet! It may not be as big as some previous ones, but it feels really coherent. The plane is nice as well with its white, orange, and blue stripes. I agree that Heartlake City Airport's plane has a cozier and more detailed interior, though. It does really highlight some of the differences between Friends and City, with City opting for capacity over comfort and function over flair.
Lego has an ongoing deal with publisher Dorling Kindersley (DK), who are producing a series of illustrated hardback books looking at different aspects of the construction toy. The first was "The Ultimate Lego Book", published in 1999. More recently, in 2009, the same publisher produced The LEGO Book, which was sold within a slipcase along with Standing Small: A celebration of 30 years of the LEGO minifigure, a smaller book focused on the minifigure. In 2012, a revised edition was published. Also in 2009, DK also published books on Lego Star Wars and a range of Lego-based sticker books.[90]
LDStructure, developed by Michael Heidemann, is a tool for analyzing ldraw parts library. With LDStructure you will get a tool that tells you which parts are required to show the current part and where the current part is used in. You will get this information within a second or even quicker. So this tool is a "needs to have" if you are working on parts for the ldraw part library.
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.
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.

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.
LEGO City enables us all to remember why we fell in love with LEGO to begin with, to remember how we all first became exposed to LEGO; as a little kid, building our first house or giving our minifigures a hospital or a police station to work in. My first set was a garage, quickly followed by a police station. Having recently found these in storage, and keen to rebuild them, having the opportunity to build something not revolving around a Jedi or an Avenger is one I keen to take advantage of.
It’s always tough to sum up a set that has the sort of price tag that this one carries; because it doesn’t necessarily offer the collectors value that a Marvel or Star Wars set will offer, it can be a little harder to justify an outlay on, in this case, a few planes and a aircraft hangar. However, if you have a love for the City range, whether it be a nostalgic look back at your childhood, the general consistently-superior design of the range, or simply because your kids want an airport to build, this one has to be recommended. Once I finished building this, I set it up in my daughter’s bedroom, and the overjoyed expression on her face, followed by the extended time taken to play with the planes and flying them all over her room, made every single minute of the build worthwhile. Watching her swirl around her room – and later, the rest of house – clutching the planes and bringing them in for landings into the hangar, reminded me of why I fell in love with LEGO in the the first place; imagination.
