Hello, aircraft lovers! Have you ever thought why airplane windows are round instead of square like the ones on your house? And why do the shades have to be up when planes take off and land? Although it’s been around since the 1920s, commercial air travel didn’t really take off until the ‘50s. That’s when airplanes started to fly at higher altitudes. It saved airlines tons of money because up there, the air is significantly less dense and aircraft use less fuel. But the early, box-shaped planes couldn’t handle that kind of pressure, so engineers presented a new cylinder-shaped cabin. And even after this upgrade, aircraft still had standard square windows, and that turned out to be a grave mistake… Other videos you might like:

What about the shades? 2:00
Must these windows be so low? 2:54
Why are they so small? 3:45
Why are the doors on the left side 5:35
… and why do they always open inward? 6:17
Are rear-facing seats much safer? 7:15 #planes #aviation #brightside SUMMARY:
– If each square window has 4 vulnerable spots, it’s likely to shatter under the enormous stress that comes from keeping the cabin pressurized for passengers at high altitudes. – When the shades are closed, flight attendants can't see what's happening outside. And since most accidents happen during take-off and landing, it's crucial that the cabin crew have a good view of what's going on outside the aircraft.
– By placing windows that low, airplane manufacturers distribute the pressure around them more evenly. – Big windows can weaken the plane’s fuselage. If it’s not as strong and gives under the pressure, the aircraft gets ripped apart.
– If they were bigger, that cabin pressure would escape faster. As a result, the air would become unbearable before the aircraft managed to reach a safe altitude. – Then why are the windows in the cockpit so big?? In this case, we have to deal with priorities. Pilots need to be able to see what's happening around them and where they’re going. – Another question connected with the doors on jumbo jets is, "Why do they always open inward?" Here’s a hint: it’s called a “plug” door. The pressure inside the plane is much higher than it is outside. This pressure literally forces the door in its socket and prevents it from opening until the pressure becomes equal. – Backward seating on a plane is much safer than the usual one. It’s because rear-facing seats provide more support for your neck, head, and back.
– But the main reason for leaving things as they are is the huge costs this renovation would involve. Music by Epidemic Sound https://www.epidemicsound.com/ Subscribe to Bright Side : https://goo.gl/rQTJZz
