Why Do All Airplane Windows Have Tiny Holes?
> Why Do All Airplane Windows Have Tiny Holes?
Those teeny tiny holes scare most of us who don’t know what they are for. Well, here we are again at the service of humanity: They are, in fact, for your safety. But how do they protect us? Let’s see.
As most of you already know, as the plane reach higher elevations, the air outside becomes thinner, containing less oxygen and pressure.
Therefore, there is a huge difference between the pressure levels inside and outside the plane.
A standard airplane window contains 3 panes.
And this famous tiny hole is on the middle pane.
Marlowe Moncur, director of technology at GKN Aerospace explains the subject:
So it means that if the outer pane somehow was broken, we'd still have the middle pane to protect us from the lack of air pressure outside.
It also helps keep the window panes from fogging up
