Cómo Funcionan los HOVERCRAFTS y Por que DESAPARECIERON

How Hovercrafts Work: It's NOT What You Think — 320 tons flying over the water at 120 km/h without touching it, crossing the English Channel in 35 minutes with 60 cars on board. The SR.N4, the largest passenger hovercraft ever built, transported millions of people for 32 years until the price of oil destroyed it. In this video, we explain how the air cushion works, why its pilots had aviation licenses and not navigation licenses, how the 1973 OPEC embargo killed a perfectly functioning technology, and what duty-free shops had to do with the final disappearance of these machines in 2000. Also discover the Soviet Zubr: the world's largest military hovercraft, capable of landing three battle tanks directly on a beach without needing a port. 🎬 If you're fascinated by the machines that changed the world, you can find the entire series here:    • Como funcionan Por DENTRO
