@amazeifystore: The crash wasn’t caused by pressure alone. It was hiding in the corners. ✈️ Every pressurization cycle stretched the Comet’s aluminum fuselage, then released the stress during descent. The square window corners concentrated those loads, allowing microscopic fatigue cracks to grow until one triggered a rapid tear. A small geometry flaw turned repetition into catastrophic damage. Would you choose rounded corners or thicker skin?
