You’ve probably noticed it many times—but have you ever wondered what that tiny hole actually does?
It’s not a crack. It’s not a defect.
✈️ It’s called a BREATHER HOLE.
So, why is it there? 👀
Aircraft windows have multiple layers. As the aircraft climbs, the pressure inside the cabin becomes higher than the pressure outside.
- That tiny hole helps manage the pressure between the window layers, allowing the stronger outer pane to handle most of the pressure difference.
It also helps reduce moisture from getting trapped between the window layers.
🔥 Tiny hole. Big job!
