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]
I did prefer the previous 3182 airport set as it had a lot more components. But, I realise that it makes more business sense to offer a little less than raise the price of an already expensive product. However, 60104 is still a nice set and is often very well discounted in the UK so, I ordered a pallet load from Tesco during their 3-for-2 which made them a half-priced no-brainer ;-)
MPDCenter, developed by Michael Heidemann, helps you to maintain all your MPD files. You can check for OMR conformity (only formal not the layout itself of course). You can extract models with all depending files. Change Author, License, Keywords, Theme, History and Filetype (LDRAW_ORG line) on the fly for all LDR files in the MPD. MPDCenter is part of the AIOI - LDraw All-In-One-Installer.
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?
Lego Games launched in 2009, was a series of Lego-themed board games designed by Cephas Howard and Reiner Knizia[77][78] in which the players usually build the playing board out of Lego bricks and then play with Lego-style players. Examples of the games include "Minotaurus", in which players roll dice to move characters within a brick-build labyrinth, "Creationary", in which players must build something which appears on a card, or "Ramses Pyramid", in which players collect gems and climb up a customisable pyramid. Like many board games, the games use dice. In Lego Games, the dice are Lego, with Lego squares with symbols on Lego studs on the dice, surrounded by rubber. The games vary from simple to complex, some are similar to "traditional" board games, while others are completely different.[79]
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...

The differences between the two jets mainly come on the top and rear of the builds. One has a larger single rear fin and two larger wings at the back, while the other has two smaller fins and the large wings positioned in the middle of the vehicle. The nose and cockpit areas are identical on both jets, and both come with stickers; the airshow logo on the wings, and a plane motif on the sides.

Parking capacity at Copenhagen Airport was greatly expanded in 2015 with the construction of a new lot as one of the first phases in an ambitious airport expansion plan scheduled to roll out in the coming decades. There are several lots: those near the terminals are very expensive, while the further-flung ones are cheaper (but have free shuttle bus service to the terminals).
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.
