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.
The last of the three aircraft is a modern biplane. This incorporates a number of rare orange elements including right and left 8 x 3 wedge plates which make up the wings and have only previously appeared in three sets, a 3 x 4 wedge brick only previously found in two sets, and a 3 x 6 round half plate with a 1 x 2 cutout which has only previous appeared in a single set in this colour and which forms the tailplanes. Similar to the two jets the tail fin is stickered rather than printed, as are the pair of 1 x 4 x 1 panels making up the sides of the cockpit. Unlike the jets, however, the instrument panel is stickered, which seems odd as there are existing printed 1 x 2 light bluish grey tiles which could have done an acceptable job. There are also a pair of stickers which represent the engine exhausts and which are applied to a couple of modified 2 x 4 x 1 1/3 bricks with curved top which sit just behind the propeller; applying these neatly to the curved surface takes a steady hand, and that’s also the case for the pair of checkerboard stickers which are stuck onto the propeller cowl. As if stickered exhausts weren’t enough, there are also a couple of light bluish grey exhaust pipes with Technic pin which emerge from the propeller cowl and run along either side of the fuselage. They’re entirely superfluous given the presence of the stickered exhausts but they still look cool regardless!

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.
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.  

As is the norm with LEGO sets these days, there are a fair few stickers in use for this item. I’m still not a fan of their use, but at this point in time, it is something I have come to expect and just get on with it now. In their defence, they do add to the overall presentation, making it that little bit harder to complain. As I said, this is my favourite of the three planes in the set, mainly because it looks superb and offers a great build experience. Seriously, I had so much fun building this. The instructions – as always – are clear, and it is not going to provide any major issues. Stability-wise, there are no concerns here, with the finished product very sturdy and, as proved by my daughter, can handle itself when being flown around the room by an excited seven-year-old. One minifigure can be seated at the controls, with suitable space for application and removal. The other pilot has its place on the top of the plane, with a single piece of black fencing to provide support for the death-defying pilot.

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.
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]
Last to be assembled is the hangar, which given its size is a surprisingly quick build – even though I’m a notoriously slow builder it took me barely ten minutes to put it together. The first step involves stacking dark bluish grey and orange plates and tiles to create a three-sided enclosure covering an area of 24 x 32 studs. Two side walls are then constructed from 1 x 6 x 5 rectangular girders topped off with dark bluish grey bricks and orange tiles, after which the roof is assembled, predominantly from a few large plates including a black 8 x 16 plate only previously available in two sets, and four dark bluish grey 6 x 24 plates which are only appearing in a set for the second time ever. A couple of stickers at the front of the structure identify it as an Airshow Hanger; to be frank, describing it as a hanger is probably exaggerating the case a bit as with its open front and rear it’s more akin to a large shelter.
LIC - LEGO Instruction Creator, developed by Jeremy Czajkowski, is a cross-platform, Python, OpenGL & Qt powered desktop application for creating and editing LEGO instruction books. LIC imports 3D models, organizes them into submodels, pages & steps, and exports the end result as images or PDF. A rich, WYSIWYG UI editor, which provides a fully interactive preview window along side a drag & drop-enabled navigation tree, to help organize and layout your book. Portions of LIC are based on work of Remi Gagne. LIC will be part of the AIOI - LDraw All-In-One-Installer.
Since the 1950s, the Lego Group has released thousands of sets with a variety of themes, including space, robots, pirates, trains, Vikings, castle, dinosaurs, undersea exploration, and wild west. Some of the classic themes that continue to the present day include Lego City (a line of sets depicting city life introduced in 1973) and Lego Technic (a line aimed at emulating complex machinery, introduced in 1977).[47]

With a price tag of £69.99/$79.99 and a piece count of 807 it means you’re paying roughly 8-9p/9-10cents per piece, which isn’t too bad when you look at it that way. This set is also quite unique in that it contains the spoilerific Giant Man brick built figure. Also in the set is the airport control tower, a baggage car and a smaller version of the Quinjet.
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]
It’s always tough to sum up a set that has the sort of price tag that this one carries; because it doesn’t necessarily offer the collectors value that a Marvel or Star Wars set will offer, it can be a little harder to justify an outlay on, in this case, a few planes and a aircraft hangar. However, if you have a love for the City range, whether it be a nostalgic look back at your childhood, the general consistently-superior design of the range, or simply because your kids want an airport to build, this one has to be recommended. Once I finished building this, I set it up in my daughter’s bedroom, and the overjoyed expression on her face, followed by the extended time taken to play with the planes and flying them all over her room, made every single minute of the build worthwhile. Watching her swirl around her room – and later, the rest of house – clutching the planes and bringing them in for landings into the hangar, reminded me of why I fell in love with LEGO in the the first place; imagination.
