@cockpitking: At 35,000 feet, the Boeing 787 Dreamliner isn’t rigid… it’s breathing. Cabin pressurisation makes the fuselage expand by several centimetres mid-flight, then contract again on descent — a constant cycle of stretch and release like a giant metal lung in the sky. You’re not just flying in it… you’re flying inside it as it quietly flexes around you. #aviation #boeing787 #aircraftengineering #flying #fyp
