Ever wonder why there’s a tiny hole at the bottom of airplane windows? The first thing you need to know is that an airplane window is made up of three panes: the outer pane which functions as the “primary structural window;” the middle pane, where the hole is located; and the inner pane, the one closest to the passenger.
