Airplane Window Holes
Have you ever flown in an airplane and sat in the window seat? If yes, you might have seen a little hole at the bottom part of the window. Did you freak out or got scared at all? Do not worry the next time you’ll fly, that tiny hole or the breather hole helps the passenger cabin maintain its safe level. When the plane goes higher, the air pressure drops; the breather holes help in balancing the pressure difference.
