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]
##### 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.

The first few bags build the small truck with carts that you see on airport runways. The truck has a "follow me" sign that I confess I have not seen at any airport. There is also a fueling tank and a rolling staircase that sits next to the plane to allow for boarding. Both the tank and the staircase are additional carts for the truck, though I am guessing not both at the same time.
```The latest wave of City sets takes us to the airport, for a wide selection of aerial adventures. Whether it’s delivering the mail, or making sure a VIP gets to where they need to go, the LEGO City Airport range has a wide selection available. With five sets of varying prices, there truly is something for everyone here. The Airport Air Show – which we are looking at today – offers two stunt jets and a vintage plane – as well as a hangar and the staff required to keep things ticking over.

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 construction of the new airport was carried out during 1964 and the airport opened on 1 November, with one runway at 1660 meters in length and 45 meters width, a small platform where aircraft could be served, and a control tower to the controller. Hans Erik Christensen, the former chief pilot at LEGO became director, and the passengers were handled in LEGO's hangar until the first terminal building was opened in the spring of 1966. The airport was continuously expanded the following years, with new facilities, terminal buildings, lounge, tax-free area and hangars where LC Johansen's studio often participated as an architect (today called the Johannsen Architects), while other work was carried out by the airport's own studio.
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]
```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.
