Why airplane windows have holes

Ever noticed the tiny hole at the bottom of a plane window? It's not just for looks, it's for your safety. Here's all you need to know!

1. The windows have small "bleed" or "breather" holes that regulate air pressure between inner and outer panes, preventing cracking or breaking from air pressure changes during flight.

2. Tiny holes in airplane windows also allow moisture to escape due to temperature and humidity differences between the cabin and outside, preventing foggy or hazy windows.

3. If the outer pane of an airplane window cracks, the tiny bleed holes between the panes allow air to flow and equalize pressure, preventing window shattering, a safety feature.

4. Airplane window bleed holes reduce noise in the cabin by allowing air to escape, which reduces the whistling or humming sound caused by air flowing over the window during flight.

5. Airplane window bleed holes regulate cabin temperature by acting as insulation, allowing air to flow between panes and keeping it cooler in hot weather and warmer in cold weather.
