Yes, the famous franchises will remain the selling point for many a LEGO fan, but for those who spent years of their childhood sitting in their lounges or bedrooms building hospitals – nay, worlds – LEGO City is everything that you could need. And for a set such as this to bring back your childhood, as well as give you a thoroughly enjoyable build experience – and the added bonus of seeing a new generation of excited faces – this is a must-have set and worth every penny.
After World City's discontinuation in 2004, it was replaced with City as System's primary town-life related theme in 2005. However, unlike its predecessor, it was not limited to sets involving rescue services like Police, Fire or Coast Guard, but also introduced the first new construction site related sets since the discontinuation of City Center in 2000. In 2006, the first new airport set that included the first jetway since 6597 Century Skyway (1994) was released, as well as the first new hospital since 6380 Emergency Treatment Center from 1987. These releases expanded City to a scope only comparable to the original Town theme, and in 2009 it even went slightly beyond that, by introducing the first farm-related System sets. Also, in that year, City followed this route to release more truly civilian town life sets such as 7641 City Corner and 7639 Camper. In 2010 City released more civilian sets including 8403 Family House and 8404 Public Transport. In 2011 City re-introduced the Space sub-theme along with some new Harbour sets. In the first wave of 2012, City had forest police and fire sets as well as some more commercial/civilian sets. The second wave of 2012 featured the introduction of the Mining theme and respective sets, as well as a hospital. In the winter of 2013, Police and Fire sets were once again focused on but, contrary to those released in the previous year, were set in the city. In the summer of 2013, the Coast Guard and Cargo subthemes were brought back.
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?" 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.
The upper and lower wings are connected by a dark bluish grey 4 x 1 x 3 tail on either side; this tail element is unique to the set in this colour, although has previously appeared in a couple of sets back in 2003 in old dark grey. The upper wing is also supported by a couple of 1 x 2 x 2 black windows placed back to back in front of the cockpit, which from the perspective of the pilot really can’t be good for visibility. The biplane has a three blade propeller and the tips of the blades are stickered prior to sliding the propeller on to a 6L axle protruding from the front of the fuselage where it’s held in place by an orange 2 x 2 brick with domed top. The last step is to attach a 1 x 4 x 2 bar to the top of the upper wing for the Wing Walker to hold on to and then we’re done with the biplane.
Parking capacity at Copenhagen Airport was greatly expanded in 2015 with the construction of a new lot as one of the first phases in an ambitious airport expansion plan scheduled to roll out in the coming decades. There are several lots: those near the terminals are very expensive, while the further-flung ones are cheaper (but have free shuttle bus service to the terminals).
