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]
The railway station, 1 Københavns Lufthavn, Kastrup Station (sometimes called CPH Airport Station and wrongly Kastrup Station), is located in Terminal 3. The station has frequent connections to Copenhagen and Malmö, as well as InterCity trains for the rest of Denmark and a few daily SJ 2000 express trains for Stockholm. The frequent Øresund trains between Copenhagen and Malmö continue in Denmark to Elsinore and in Sweden to a number of destinations in Scania and other parts of Götaland. The travel time to Copenhagen Central Station is 12 minutes, and 20 minutes to Malmö Central Station.
Lego also initiated a robotics line of toys called 'Mindstorms' in 1999, and has continued to expand and update this range ever since. The roots of the product originate from a programmable brick developed at the MIT Media Lab, and the name is taken from a paper by Seymour Papert, a computer scientist and educator who developed the educational theory of constructionism, and whose research was at times funded by the Lego Group.[51]

So that's it... It's the first passenger airport set released in 6 years.  It comes with a jet, 6 minifigures, a terminal, and some equipment for servicing the aircraft.  Should you get it?  After getting it, I'm glad I got it on sale, but I'm still not sure it was worth what I paid.  I think it needs at least another terminal worker and then a pilot and flight attendant.  Also you're paying for a lot of BURPs to help smooth the aircraft out. The age range listed is 6-12 years old so clearly it is not meant for old farts like me looking for a good building experience.  However, if you're a LEGO CITY fan and you build your own MOCs to go with your city, it has some good additions.  If you're looking to build an airport terminal of your own, you'll find some useful parts to make it realistic.  We'll see if it takes another 6 years for an upgrade.
The mechanic is a rather basic design, with an all-blue colour and a work shirt pattern. He comes equipped with a walkie-talkie and a full tool truck, containing every piece of equipment a mechanic could need. The airport worker looks like every other workman from The LEGO Movie that joined Emmet in a chorus of Everything is Awesome, and is a nostalgic hark bark to the old construction figures that I grew up playing with.

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?

I cannot stress just how much I love this item, it may well be the highlight of the whole set. LEGO have released bi-planes before of similar design, but it still something to marvel over. Harking back to those older days of LEGO relying on imagination and not movie franchises, this is what we had to play with, and it is great to be able to relive that in today’s world.

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.
