China's Longest Underwater Highway Tunnel Has a Colorful LED Ceiling to Prevent Driver FatigueChina has just opened its longest underwater highway tunnel to date, and it has a colorful LED ceiling specially built to prevent driver fatigue.The 10.79-kilometer tunnel is located under Lake Taihu, Jiangsu Province, just 50 kilometers shy of Shanghai. Construction started on January 9th, 2018. Four years, 9.9 billion yuan ($1.56 billion) and 2 million cubic meters of concrete later, the Taihu tunnel is officially complete and open to vehicle traffic.At 17.45 meters wide, the two-way tunnel houses six lanes and is predicted to reduce traveling time between Shanghai and Nanjing, Jiangsu's capital. It is also expected to segue traffic from the crowded cities next to Lake Taihu to those located in the Yangtze River delta area where it will help boost economic development.Image: FeatureChina#tunnel #LED #China

Red Bull Stunt Pilot Dario Costa Flew an Airplane Through TWO Tunnels at 150 Miles per HourDario Costa, a professional race and stunt pilot, set a world record by flying through two tunnels at an average speed of 245 kph (152.2 mph) on September 4, 2021. Costa flew in his modified Zivko Edge 540 race plane inside of the dual Catalca Tunnels on Turkey’s Northern Marmara Highway.With over two decades of flying under his belt, the 41-year-old pilot clocked over 5000 hours in the cockpit, with more than half of those hours in high-performance aerobatics.  He became the first Italian to win in the Red Bull Air Race Challenger Class. For years, Costa dreamt of the Tunnel Pass, believed to be his most challenging stunt yet.“Everything seemed to be happening so fast, but when I got out of the first tunnel, the plane started to move to the right because of the crosswinds and in my head, everything slowed down in that moment, I reacted and just focused on getting the plane back on the right path to enter the other tunnel. Then in my mind, everything sped up all over again.” Said Costa.Costa was averaging 245 kph while managing changes in the second tunnel. After the plane got out of the other side, he made a celebratory loop before landing. The flight in the tunnel was recognized with a Guinness World Record for Longest Tunnel Flown through with an Aeroplane at 1,730m. There are four other records set in this exhibition: first Aeroplane flight through a tunnel, longest flight under a solid obstacle, first aeroplane flight through two tunnels and first aeroplane takeoff from a tunnel.#RedBull #WorldRecord #GuinnessWorldRecord #Airplane #Aviation #Tunnel #DarioCosta
