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.
I like the nod to the classic LEGO Ideas Book with the 'Follow Me' sticker, but overall I think the F-18 type jet is redundant, making the whole thing over-priced. Had it been presented in a different colour scheme from the Viggen, and maybe a bit of a sleeker or more agile design in itself, it might have been a worthwhile inclusion. But as it is, it just superficially looks like two fairly similar aircraft, and thus quite a bit less value for money as a set.
My six year old grandson loves Lego's. His daddy is a pilot so we got him this Lego City Airport for his birthday. Wow! He couldn't wait to put it together! It was organized in bags (which I didn't know) and this prevents overwhelming a little person. At least that's what my son said! He did indeed help our grandson put it together, but that was expected as a father/son project. It is so realistic! I love the tower especially. It has moving parts and all kinds of nifty little things - like luggage! The plane has a bathroom too! This is a great addition to anyone who loves Lego's!
If you don’t own Black Panther Pursuit or any of the sets that included Captain America, I guess it would a plus getting the both of them in this set but Super Heroes collectors tend to be completionists, so I think that scenario will be particularly rare. I guess you could always sell your spares on the secondary market, but really, who wants to do that?
The final two minifigures are the Biplane Pilot and the intrepid Wing Walker. Both of these minifigures share the same white torso which is printed with a flight suit design overlaid with dark red and bright light orange flames plus a logo over the left breast. The torso design is superb and it can at present only be found in this set. Both minifigures are provided with a reddish brown aviator cap and dark bluish grey goggles, and the pilot (below left) also gets an alternative to this headgear in the form of medium dark flesh mid-length hair which has only ever appeared in five sets in this colour.
