The Singapore Flyer is tallest Skywheel on Earth, rising 165 metres into the sky. It can whisk 1,260 passengers around hourly to see a stunning 45 km panorama of three different countries below. Twice the height of the Statue of Liberty, the ground-breaking observation wheel effortlessly rotates 28 luxury capsules through the sky, each carrying 28 passengers. Extraordinary engineering ensures the wheel stands firm against the area's monsoon rains, thunderstorms and dangerous Sumatra wind squalls. But the Singapore Flyer wasn't built in a day. It stands on the shoulders of historic engineering achievements that have allowed it to grow so tall. This film explores five landmark observation wheels - including the original Ferris Wheel and London Eye - that each feature a major technological innovation that contributed to the construction of the Singapore Flyer.
