The Mystery Of The Plane Window’s Hole

If you have ever sat in the window seat of an airplane and have keen observation skills, you might have noticed the existence of a tiny hole at the bottom of the window. Often people who see it consider its presence trivial. However, the gap is there to reduce the internal pressure of the aircraft.

When the plane surges to new heights, the interior of the jet develops pressure. This is why some of us feel uneasiness in planes. Yet this tiny aperture is left there to release excessive force, preventing the window from breaking from the immense compression.
