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]
The road distance is to Billund 3 kilometres (2 mi), to Vejle 28 kilometres (17 mi), to Kolding 41 kilometres (25 mi), to Esbjerg 61 kilometres (38 mi) and to Aarhus 98 kilometres (61 mi). There are airport buses to Horsens, Skanderborg and Aarhus. Eight additional bus services operate from the airport. There are six parking zones named after countries of the world, USA, Australia, Kenya, Spain, Egypt and Greenland. Three of the zones are connected by a shuttle bus, the other three being within walking distance.
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.

The two stunt jets included here actually have some similarity in the basic design and colour scheme to the main piece seen in the Marvel Super Heroes Avenjet Space Mission set. With that being said, I loved the Avenjet in that particular set, so any similarity holds no issue with me. The red and white colours work really well together, and it looks like something you would genuinely see flying through the sky at an air show. I really love it when LEGO truly capture the essence of what you are building, and they do that here. The jets themselves, as I said before, are similar to previously-released jets, and therefore the builds won’t come as any main surprise. That shouldn’t detract from the product, however, as it is a prime example of LEGO finding a winning formula and not really needing to change it.
Every good airport needs a hangar for the planes, and this is no exception. The satisfactory hangar included here does come across as rather basic, and while it doesn’t detract from the overall package, it isn’t going to swing your decision over whether to purchase this (and truthfully, I think you would have already made that decision before you come to the hangar). The design itself is simple, with the build unlikely to take you more than 10 minutes. That being said, it is a well-built piece and doesn’t feel flimsy, which was the impression I had when I first saw a picture of it. The criss-cross pieces towards the base give it a firm foundation, and there are plenty of long pieces which add further stability to it. Plane-wise, it is best suited for the old-fashioned vehicle, with the orange colouring in the design going well with the plane. Only a couple of stickers in use here, with just the AIRSHOW HANGAR words needing to be added.
There are 3 cardboard boxes with more Easter eggs. We get a few references to Marvel organisations such as A.I.M., who you may remember from Iron Man 3 as an R&D agency run by Aldrich Killian, Hammer, one of Stark Industries primary rivals which made an appearance in Iron Man 2, bankrolling Whiplash and finally a box with the Stark Industries logo on it.
I'm not sure what to make of the set yet. I like the planes (although that biplane really doesn't need the bubble canopy). The idea of adding a hangar is interesting and I don't mind that it's a bit open. But the fact that it'll only house one of the three planes is annoying. Having said that, I'm not sure what you could do about it. Tripling the hangar would make it big and boring and push the price up. Could they have done two planes and a double hangar?
If you’ve watched Captain America: Civil War, you’d know that the airport is the scene of one of the coolest superhero showdowns ever, with Team Iron Man and Team Captain America duking it out on the tarmac. The scene is chaotic, gorgeously choreographed and most importantly stolen by the likes of Spider-Man (not included in this set) and Ant-Man transforming into the aptly named Giant-Man.
This set is designed for children aged 6+, and one of the ways that it is suitable for them is the inclusion of separate instruction booklets and numbered bags for the different parts of the set (see my post about LEGO age range suitability here).  A younger modeller can build the plane or other item of their choice as soon as they open the box. It's not so much one big set as 5 different parts which make a whole scene. My 7 year old son chose to build a jet first of all...
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.
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.
