By 1954, Christiansen's son, Godtfred, had become the junior managing director of the Lego Group. 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. In 1958, the modern brick design was developed; it took five years to find the right material for it, ABS (acrylonitrile butadiene styrene) polymer. The modern Lego brick design was patented on 28 January 1958.
With a price tag of £69.99/$79.99 and a piece count of 807 it means you’re paying roughly 8-9p/9-10cents per piece, which isn’t too bad when you look at it that way. This set is also quite unique in that it contains the spoilerific Giant Man brick built figure. Also in the set is the airport control tower, a baggage car and a smaller version of the Quinjet.
Bag 3 starts the aircraft and includes 3 minifigures (2 passengers and a pilot) The aircraft has the standard wings and fuselage sections. I am not a fan of the giant wing piece as it limits the number of seats. It does however help to make the aircraft more realistic. Given the size of the aircraft, there are only 5 seats for passengers which is rather disappointing.
Manufacturing of Lego bricks occurs at several locations around the world. Moulding is done in Billund, Denmark; Nyíregyháza, Hungary; Monterrey, Mexico and most recently in Jiaxing, China. Brick decorations and packaging are done at plants in Denmark, Hungary, Mexico and Kladno in the Czech Republic. The Lego Group estimates that in five decades it has produced 400 billion Lego blocks. Annual production of Lego bricks averages approximately 36 billion, or about 1140 elements per second. According to an article in BusinessWeek in 2006, Lego could be considered the world's No. 1 tire manufacturer; the factory produces about 306 million small rubber tires a year. The claim was reiterated in 2012.
Even in terms of play value it mostly seems to be a trade-off — 60104 loses the vending machine, cafe, baggage x-ray scanner, and a few seats on the plane but gains a baggage conveyor, a restroom, a refueling tank for the plane, an additional minifigure, and more seats in the waiting area. It's pretty nice to see the value of a LEGO air terminal remain fairly stable even though the price has not increased.
Structurally, the plane model is sound and very well-built. A little too well-built in some areas you would say, but they are necessary measures like the awkward humps in the interior of the plane you will discover. Space is very wisely used in this model as they’ve managed to fit a proper looking cockpit for 2 pilots and even managed to squeeze in a sink, a mini-bar with the one drink, seats for 6 more passengers and even a tight little space of a washroom. That door hinge though, is a work of art.
Minifigures are the real draw, although we’ve seen most of these characters before, but the completist will want them in their updated costumes. Among the figures are Iron Man, War Machine, Scarlet Witch, Agent 13, Captain America, Winter Soldier, an Ant-Man micro-figure and of course the Giant-Man Brick built figure. These are all fantastic, and it’s the first outing for the Agent 13 figure. The printing on these figures is excellently detailed; in particular Iron Man and War Machine, who both get leg printing, are fantastic. I’m one-hundred percent sure, but Agent 13 has what looks like a new hairpiece that is really well sculpted. And this time around, Scarlet Witch gets correctly coloured hex blasts. If there is a slight downer on the mini,figure side of things, it’s Captain America. Sadly we’ve seen it all before and despite the new detailed printing on his torso, he just looks really plain when stood next to the others in this set.
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.
