The 152,455-piece Lego Rolls-Royce Trent engine may be the most complex Lego machine ever built, but it's nothing compared to the real thing. This awe-inspiring time lapse video shows how they build the turbo-fan engine that powers some of the most popular airliners in the world, including the Boeing 787 Dreamliner.
The Trent powers the Airbus A330, A340, A350 and A380, plus the Boeing 777 and 787. The Dreamliner is the only commercial airplane that can actually use both the General Electric GEnx and the RR Trent 1000. The latter is a 12,710 pound (5.7 metric ton) machine that is 9.35 feet in diameter. This variant is capable of creating 75,000 pounds of force (330kN).
