^ Jump up to: a b Alexander, Ruth (3 December 2012). "How tall can a Lego tower get?". BBC News. Archived from the original on 4 December 2012. Retrieved 4 December 2012. The average maximum force the bricks can stand is 4,240N. That's equivalent to a mass of 432 kg (950lbs). If you divide that by the mass of a single brick, which is 1.152g, then you get the grand total of bricks a single piece of Lego could support: 375,000. So, 375,000 bricks towering 3.5 kilometers (2.17 miles) high is what it would take to break a Lego brick.
Since 1963, Lego pieces have been manufactured from a strong, resilient plastic known as acrylonitrile butadiene styrene (ABS). 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. 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. 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. Lego has a self-imposed 2030 deadline to find a more eco-friendly alternative to the ABS plastic it currently uses in its bricks.
Correct me if I'm wrong, but is the hangar only large enough to house the biplane? A bit of a cock-up if that's the case. As good as the planes are, the hangar is a major failing. It looks like it's only about 30-40 pieces; just a bunch of big plates, some prefab cross-bracing and ... errrm ... air. Not so much a "hangar" as an aviation-equivalent of a car port!
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.
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.
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.
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!
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.
Compared to other major European hub airports, like Charles de Gaulle or Heathrow, CPH has a similar number of connections, but is much smaller in both actual size and passenger volumes, and can provide a calmer, more pleasant experience. Its location in the south of Scandinavia makes reaching most European destinations reasonable, and flying to destinations in the Baltic region and in Eastern Europe generally only takes half the time as from major hub airports in Western Europe.
