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?" 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.
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.
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.
