In 1955, two ferries sank along the Akashi Strait, Japan, killing 168 children. It led to a 30 year research on designing a bridge that would link the Awaji Island to Kobe; the bridge would also have to be able to withstand severe earthquakes and typhoons, a norm in that area. In 1988, Japan began construction of the world’s longest, highest and most expensive suspension bridge, the Akashi Kaikyo Bridge. The episode presents a stage by stage look at the construction of the suspension bridge, and the obstacles faced in its construction, including the Kobe earthquake in 1995.

And explains how the Kingda Ka utilises a hydraulic launch system to launch riders to a speed of 206km/h in 3 seconds.

What began as a racing track, and thanks to Adolf Hitler’s World War II propaganda efforts, the track grew into a sophisticated high-speed road system, linking to almost all the major cities in Germany. The Autobahn boasts of having super thick road beds, 4% or less grades, wide lanes, and build on layers of technology. The Autobahn allows vehicles to travel at speeds exceeding 160km/h for roughly 2/3 of its roads. The episode profiles the operations of the highway cops, and their reliance on technology in training, monitoring of roads and various methods of arrest. It also looks at the ADAC, an automobile club, which provides on the spot road assistance. Nicknamed ‘The Yellow Angels’, they also provide air medical rescue. The system of maintenance of the Autobahn is also examined. All this infrastructure makes this mega structure into one of the world’s most safest super highway.
