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.
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.
I purchased this set the day it was released for my LEGO City, as an upgrade from my previous airport (10159 Airport from 2004). First off, the build is great and although it's not very challenging, it's exciting to see the plane come to life and the use of the big plane pieces (eg. the nose, the wings, the tail etc.) was new to me, though I know there have been a number of planes in the past that use these pieces. There are 4 instruction booklets (2 for the plane, one for the airport, and one for the luggage/fuel/stairs car), 8 numbered bags, and two separate bags with the bigger pieces in. This makes the build very easy to follow. The completed set is very grand (especially the plane) in scale, and great looking. It's nice to see that a different colour scheme been used for the plane as opposed to the usual red and white or blue and white colours as seen in previous sets. The plane is HUGE, with a wingspan of around 2 32-wide baseplates (bare this in mind if you want to make a runway). However, despite its huge size, the inside of the plane is very bare. There are 5 seats for the passengers, another one facing backwards which I presume is for the cabin crew (although there isn't a cabin crew minifigure, which would have been a nice addition), and two seats in the cockpit. There's a tiny bathroom at the back of the plane, and a small galley area at the front with a sink and cupboard. There's easily room for a sixth chair in the plane, which I think should have been included, and the space within the plane could've been arranged better to fully optimise the area. The airport terminal has a very nice modern look, and includes the revolving door, tower, waiting area, security scanner and check in desk with luggage conveyor. Although this sounds like a lot of features, the inside of the terminal is, again, very bare and the space could've been used better. There are only 4 seats in the waiting area, and a lot of the space is taken up by the revolving door. The operational conveyor belt for the luggage is a nice touch, though, and there is a fair bit of playability within. The service car is a nice addition to this set and gives it more playability. All the trailers (fuel, stairs and luggage) connect together and attach to the service car, which has a really cool "follow me" sign on the back. This is a really nice addition to the set. Overall, I really like this set because of how it looks and because there's plenty of opportunity for play, but I think a lot more thought could've gone into maximising the space within the plane and the airport. Some more minifigures would have been good, such as a member of the cabin crew, a check-in clerk and a security officer. The value for money is okay with this set, as you do get a lot of big pieces, but the bare interiors are a little disappointing for the price you pay.

Manufacturing of Lego bricks occurs at several locations around the world. Moulding is done in Billund, Denmark; Nyíregyháza, Hungary; Monterrey, Mexico and most recently in Jiaxing, China. Brick decorations and packaging are done at plants in Denmark, Hungary, Mexico and Kladno in the Czech Republic. The Lego Group estimates that in five decades it has produced 400 billion Lego blocks.[41] Annual production of Lego bricks averages approximately 36 billion, or about 1140 elements per second. According to an article in BusinessWeek in 2006, Lego could be considered the world's No. 1 tire manufacturer; the factory produces about 306 million small rubber tires a year.[42] The claim was reiterated in 2012.[43]
I would also have liked a proper Ant-Man minifig – we get a micro Ant-Man, Giant-Man but not a regular-sized Ant-Man. There is a minifigure-sized Scott Lang hole in this set, and I think LEGO have wasted a great opportunity inserting a really popular and coveted minifigure into their flagship Civil War set. I would even gladly trade Cap and Bucky for one Ant-Man minifig.
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.
