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]

Lego (Danish: [ˈleːɡo];[1][2] stylised as LEGO) is a line of plastic construction toys that are manufactured by The Lego Group, a privately held company based in Billund, Denmark. The company's flagship product, Lego, consists of colourful interlocking plastic bricks accompanying an array of gears, figurines called minifigures, and various other parts. Lego pieces can be assembled and connected in many ways to construct objects including vehicles, buildings, and working robots. Anything constructed can then be taken apart again, and the pieces used to make other objects.[3][4]
@DrDave : My thoughts were not that the hangar should be big enough to hold *all* aircraft simultaneously - which would, indeed, make it huge! - but that it should at least be big enough to hold any one of them. Just a few studs wider should cover the wingspan of either jet (judging from the photos). Add a few centimetres to the height - by whatever construction means - and that'll accommodate the oversized tail on the Viggen-styled plane. If/when I pick up this set, that's the mods I'll be making to it.
Young builders and adventurers will love conquering a construction challenge and then taking a trip with LEGO City Airlines. This set features an airport terminal facade with control tower, luggage conveyor belt, revolving doors, and security check. The passenger airplane has a door that opens, a galley, and a lavatory, and there is also a luggage trailer, a fuel trailer, a mobile stairway, and an airport service car. Great for inspiring imaginative play, this impressive set can be combined with others in the LEGO City Airport collection for endless role play and configuration options.
```The intelligent brick can be programmed using official software available for Windows and Mac computers, and is downloaded onto the brick via Bluetooth or a USB cable. There are also several unofficial programs and compatible programming languages that have been made to work with the brick, and many books have been written to support this community.[52]

The box set weighs a little over 2kg and has about 694 pieces in total, including 6 minifigures: a pilot, 3 airport workers, a male and a female passenger. The whole build would get you almost an entire airport facade with a pretty big passenger plane, an airport/control tower build, and an airport service car that tows with it a luggage, fuel and and mobile stairway.
Over the years, Lego has licensed themes from numerous cartoon and film franchises and even some from video games. These include Batman, Indiana Jones, Pirates of the Caribbean, Harry Potter, Star Wars, and Minecraft. Although some of the licensed themes, Lego Star Wars and Lego Indiana Jones, had highly successful sales, Lego has expressed a desire to rely more upon their own characters and classic themes, and less upon licensed themes related to movie releases.[48]

# 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.

By 1954, Christiansen's son, Godtfred, had become the junior managing director of the Lego Group.[13] It was his conversation with an overseas buyer that led to the idea of a toy system. Godtfred saw the immense potential in Lego bricks to become a system for creative play, but the bricks still had some problems from a technical standpoint: their locking ability was limited and they were not versatile.[3] In 1958, the modern brick design was developed; it took five years to find the right material for it, ABS (acrylonitrile butadiene styrene) polymer.[11][12] The modern Lego brick design was patented on 28 January 1958.[15]
The Lego Group's motto is det bedste er ikke for godt which means roughly "only the best is the best" (more literally "the best is never too good").[8] This motto, which is still used today, was created by Christiansen to encourage his employees never to skimp on quality, a value he believed in strongly.[8] By 1951 plastic toys accounted for half of the Lego company's output, even though the Danish trade magazine Legetøjs-Tidende ("Toy-Times"), visiting the Lego factory in Billund in the early 1950s, felt that plastic would never be able to replace traditional wooden toys.[13] Although a common sentiment, Lego toys seem to have become a significant exception to the dislike of plastic in children's toys, due in part to the high standards set by Ole Kirk.[14]

# Other than the planes, I do find it unfortunate that the Friends set focuses on shopping and food like so many Friends sets, and I also think it is unfortunate that the City terminal only has the basics of the airport structure in the control tower and service truck. Having a control tower for the Friends set would have been great. Having a gift shop/cafe for the City terminal would have been a worthwhile addition and not something we have seen in many City sets.

They are still being published in Europe by AMEET. Bionicle comics, also written by Farshtey, are compiled into graphic novels and were released by Papercutz. This series ended in 2009, after nine years.[91]

Thanks for the great review and comparison. I've thought about getting the Friends Airport for my daughter, as we both like the amount of detail inside the plane. Why would Lego think that boys don't care as much about detail? I love the wider body planes, but it's a shame they're not producing the runway plates, or including them in the airport sets, anymore. I agree with ZeeBricks that if they're not going to include everything an airport needs (although as expensive as price/piece these sets are getting it would cost a fortune) they should sell smaller sets that can be added together. Now that I'm feeling nostalgic for classic airport I might rebuild my 6392 and dust off my 6396 and set them up tonight, it's time for some serious swooshing :)
The main constituents of the set are a tanker truck, three aircraft and a hangar. Each of these gets its own instruction booklet and bags of elements. First up is the tanker truck (below) which at only four studs wide and less than ten studs in length reminds me of the 4-stud wide vehicles of my youth. This impression is reinforced by the inclusion of a couple of late 70’s-style 2 x 4 mudguards in the build.
LEGO CITY has some recurring themes that can get old after a while and obviously are meant for younger LEGO fans.  The Fire and Police themes within CITY quickly come to mind as it seems like they have a new run each year.  The Airport theme is one of those that doesn't quite occur every year.  The last airport set was released in 2010 and was set #3182.  This year (2016) another airport was released.  #60104, Airport Passenger Terminal, was released on 1 August 2016 in the US.  It costs \$99.99 in the US and contains 694 pieces or \$0.144 per piece.  I picked the set up from Amazon at 20% off or \$80 (\$0.115 per piece).  Yay sales!  Onto the review...
