1. Secret Crew Bunks
Many long-haul planes have hidden compartments above or below the passenger cabin where crew members sleep during flights.
2. Lightning-Proof Design
Airplanes get struck by lightning about once a year on average, but they’re built to safely handle it.
3. Round Windows Save Lives
Square windows once caused structural failures. Round windows distribute stress evenly, preventing cracks.
4. Air Isn’t as Fresh as You Think
About 50% of cabin air is recycled; the rest is fresh, pressurized air from outside.
5. Wings Can Flex Amazingly
In turbulence, a plane’s wings can bend upward as much as 25 feet without breaking.
6. Fastest Commercial Plane
The Concorde could fly from New York to London in under 3.5 hours, more than twice the speed of today’s jets.
7. Tiny Triangles on the Wall
Those small black triangles above some windows help the crew locate the plane’s wings quickly for visual checks.
8. Why Cabin Lights Dim
During takeoff and landing, lights are dimmed so your eyes adjust in case of an emergency evacuation.
9. Brake-Free Takeoffs
Commercial jets typically don’t use brakes while taking off; the engines do all the work.
10. Planes Are Cleaner Than You Think
The air is filtered every few minutes with HEPA filters, trapping 99.9% of bacteria and viruses.
