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 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]
Attention then shifts to construction of the three aircraft. When I first spied this set I assumed that the two red jets were the same, but closer examination reveals a number of differences. First up is a red jet with a canard wing configuration as seen in the Saab Viggen amongst others. The lower fuselage is fashioned from a number of double and triple inverted 45 degree slopes with a pair of 1 x 14 Technic bricks running through the centre; there’s no obvious reason for Technic bricks to be used in this situation – standard 1 x 14 bricks would have done the job just as well - so I assume that LEGO just happened to have a bunch of them lying around…. A printed black 1 x 2 tile in the cockpit represents the instrument panel, while a substantial air intake is attached on either side of the fuselage at a 90 degree angle by way of brackets.
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]
This set is designed for children aged 6+, and one of the ways that it is suitable for them is the inclusion of separate instruction booklets and numbered bags for the different parts of the set (see my post about LEGO age range suitability here).  A younger modeller can build the plane or other item of their choice as soon as they open the box. It's not so much one big set as 5 different parts which make a whole scene. My 7 year old son chose to build a jet first of all...

### Lego pieces of all varieties constitute a universal system. Despite variation in the design and the purposes of individual pieces over the years, each piece remains compatible in some way with existing pieces. Lego bricks from 1958 still interlock with those made in the current time, and Lego sets for young children are compatible with those made for teenagers. Six bricks of 2 × 4 studs[28] can be combined in 915,103,765 ways.[29]

```Help the pilot and the airport worker get the packages ready for delivery! Use the hand truck to load the packages on the airport service car and drive them to the back of the plane for loading. Fit all the packages in and then make sure the back is closed before letting the pilot know he's good to go. Take off for some fun package delivery in LEGO® City!

It’s been three years since the release of the most recent City Airport set, namely, 60019 Stunt Plane, and a full six years since LEGO gave us a number of Airport releases at any one time. Of the five summer 2016 Airport releases, 60103 Airport Air Show was one of those that I was most interested to get my hands on, and I’m pleased to be able to bring you a review of it today.
From mid-2009, the airport was served by 9 airlines flying regular flight service, of which KLM had the busiest route with over 200,000 annual passengers to Amsterdam Schiphol. In 2011, Ryanair announced that Billund Airport with effect from 25 March 2012 would be the base for two Boeing 737 aircraft. At the same time Ryanair published 5 new routes, so that, from the summer of 2012, they would fly to 19 destinations.
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.
There are 3 cardboard boxes with more Easter eggs. We get a few references to Marvel organisations such as A.I.M., who you may remember from Iron Man 3 as an R&D agency run by Aldrich Killian, Hammer, one of Stark Industries primary rivals which made an appearance in Iron Man 2, bankrolling Whiplash and finally a box with the Stark Industries logo on it.
My personal favourite of the three planes included in this set, the design is superb and really captures the look and feel of the old-fashioned airplane that it is based on. The build isn’t too complex, and it really is a joy to see the final product come together. The plane has a distinct orange colour scheme, with some black and grey thrown in, and the shades work well together.
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.
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.
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...
