This was bought for my son's 5th birthday. If your kid likes to really play with the sets like mine does (not just bought for building it) be aware that the door of the airplane likes to pop off if it is not opened/closed just the right way with gentle hands. My son is a typical rambunctious boy and is not great at opening/closing things gingerly, so the door presents a bit of a problem for him. He doesn't have the dexterity or patience to snap the two tiny joint pieces onto the little pole just so yet, so whenever the door comes off he gets frustrated and needs help. Which is fine, we help him and he will eventually learn to do it himself, but just wanted to make y'all aware of this in case you have someone who is picky about the door opening and closing easily/correctly :) I know some little ones get fussy about these things!

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]
This detailed model features a classic red, black and grey colour scheme, large driver's cab with detailed dashboard, wing mirrors, opening tool storage compartment, 4-cylinder engine with moving pistons, twin-axle steering, double rear axle and chunky tires. Activate the boom to position the water cannon and extinguish the flames! This Power Functions upgradable model can be rebuilt to create an awesome Fire Rescue Vehicle!
Lego also initiated a robotics line of toys called 'Mindstorms' in 1999, and has continued to expand and update this range ever since. The roots of the product originate from a programmable brick developed at the MIT Media Lab, and the name is taken from a paper by Seymour Papert, a computer scientist and educator who developed the educational theory of constructionism, and whose research was at times funded by the Lego Group.[51]
Agent 13 has a pretty plain appearance, with caramel-coloured wavy hair, and a black, spy-like top. Her torso has some nice details, with sharp, angular lines that all combine to form a rough outline of an upside down star. She has plain sand blue pants and rocks a sub-machine gun accessory. I like regular LEGO firearms, so it’s very nice to get one in this set as they’re fairly uncommon.
The body of the plane is built with five seats for passengers. The wings are added next with what I think are filler stickers added to the top of the wings. There is a small galley with sink and oven in the front of the plane right behind the cockpit. The cockpit uses only one sticker to show navigation equipment - the other is printed, which is always welcome (though not a new piece). A lavatory is installed in the back, and then the inside is complete. There is an odd choice for the door to the lav - a swinging door. Not much opportunity for privacy!

Basically, the only thing that the two sets have in common is that they both have planes. However there is quite a bit of difference on the inside of the planes. There are a lot more details in the Friends plane. In addition to the seats, there is a rolling service cart complete with refreshments, emergency lighting as well as a larger galley and lav in the back of the plane.

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.
