How A Jet Airliner Works– 6 Million Parts, One Failure Away From Disaster

Ever wondered what keeps a six-million-part machine safely in the sky at 35,000 feet? This video breaks down the extraordinary engineering inside a modern jet airliner — from the carbon fiber skeleton of the Boeing 787 Dreamliner to the jet engines running hotter than the melting point of their own turbine blades.We explore every major system: how the wings generate 350,000 kilograms of lift, why the cabin stays breathable at altitudes where outside pressure drops to just 3.5 psi, what fly-by-wire flight controls actually do, how landing gear absorbs a 3-meter-per-second touchdown, and the emergency Ram Air Turbine that deploys when everything else fails — the last line of defense that saved Air Transat Flight 236.
