@cockpitking: THIS WALL IS THINNER THAN YOUR PHONE It feels solid. Safe. It isn’t thick. On a Boeing 737, the fuselage skin is just a few millimetres—thinner than your smartphone. Yet it’s holding back a huge pressure difference at 35,000 feet… every second you’re onboard. Expand. Contract. Repeat. Thousands of times across its life. Because in aviation… strength isn’t thickness. It’s design. #boeing737 #aircraftstructure #pressurisation #aviationengineering #avgeek
