Correct - the hanger can only accommodate the biplane. That having been said, in order to accommodate the other aircraft too the hangar would have to be huge, with an enormous footprint, and a substantially increased parts count. As a result, I'd estimate a price up to double the current RRP which I suspect few of the target market would pay. LEGO therefore got the size of the hanger right IMHO.

In December 2012, the BBC's More or Less radio program asked the Open University's engineering department to determine "how many Lego bricks, stacked one on top of the other, it would take for the weight to destroy the bottom brick?"[44] Using a hydraulic testing machine, the engineering department determined the average maximum force a 2×2 Lego brick can stand is 4,240 newtons; since an average 2×2 Lego brick has a mass of 1.152 grams (0.0406 oz), according to their calculations it would take a stack of 375,000 bricks to cause the bottom brick to collapse, which represents a stack 3,591 metres (11,781 ft) in height.[44]
Bag 7 finished off the front facade adds in a metal detector and the baggage check-in station.  I guess you enter from the right and then maybe the revolving doors are where you can walk out to the plane.  I'm not really sure anymore.  The conveyor belt is a nice addition to the set for playability and is set up so you can pull the baggage cart right next to it.  
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.
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 ;-)
Pack your bags and get ready to go on vacation! Head to the airport and check in at the terminal. Put your luggage on the conveyor belt and watch it get loaded onto the passenger airplane. Go through security and then head out the revolving doors to the loading area. Climb the stairs and get buckled in, your trip is about to start! This creative play building toy includes 6 minifigures.

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.

My six year old grandson loves Lego's. His daddy is a pilot so we got him this Lego City Airport for his birthday. Wow! He couldn't wait to put it together! It was organized in bags (which I didn't know) and this prevents overwhelming a little person. At least that's what my son said! He did indeed help our grandson put it together, but that was expected as a father/son project. It is so realistic! I love the tower especially. It has moving parts and all kinds of nifty little things - like luggage! The plane has a bathroom too! This is a great addition to anyone who loves Lego's!

I like the nod to the classic LEGO Ideas Book with the 'Follow Me' sticker, but overall I think the F-18 type jet is redundant, making the whole thing over-priced. Had it been presented in a different colour scheme from the Viggen, and maybe a bit of a sleeker or more agile design in itself, it might have been a worthwhile inclusion. But as it is, it just superficially looks like two fairly similar aircraft, and thus quite a bit less value for money as a set.

The airport handles an average of more than two million passengers a year, and millions of pounds of cargo. The airport's main runway can handle airliners as large as the Boeing 747, although most passengers arrive on smaller aeroplanes, such as ATR-42s, Boeing 737s and Boeing 757s. Boeing 747 activity at this airport is almost exclusively limited to cargo flights.

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.
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]
