^ Jump up to: a b Alexander, Ruth (3 December 2012). "How tall can a Lego tower get?". BBC News. Archived from the original on 4 December 2012. Retrieved 4 December 2012. The average maximum force the bricks can stand is 4,240N. That's equivalent to a mass of 432 kg (950lbs). If you divide that by the mass of a single brick, which is 1.152g, then you get the grand total of bricks a single piece of Lego could support: 375,000. So, 375,000 bricks towering 3.5 kilometers (2.17 miles) high is what it would take to break a Lego brick.
Bag 4 finishes the fuselage and all that is left are the engines and tail section. You'll notice that this aircraft has a bathroom on board as well as some storage for a non-existent flight attendant. I think this is the first time that LEGO has put some additional details into aircraft besides just seats. Also there is only one pilot for a 2 seat cockpit in the set.
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.
