Why Airplane Windows Have Tiny Holes (It Could Save Your Life)

What Happened: The Engineering Behind the Hole

Every commercial aircraft window you’ve ever peered through actually consists of three separate layers working in harmony. The outermost pane bears the structural load and pressure difference between the cabin and the thin air outside. The middle layer serves as a backup in case the outer pane fails. And the inner layer? That’s just there to protect the real windows from your scratches and fingerprints.

8 World's Most Terrifying Airport Landings Revealed

What Makes These Airports So Dangerous

Airport landings that would make even frequent flyers grip their armrests aren’t just the stuff of nightmares—they’re very real challenges that pilots face at airports around the world. Mental Floss has identified eight airports where geography, weather conditions, and engineering limitations create landing scenarios that test the limits of aviation expertise.

These aren’t your typical runway challenges. We’re talking about airports where pilots must navigate toward mountains before executing sharp turns, runways so short that only smaller aircraft are permitted, and landing strips that until recently intersected with busy public roads.
