  • Hey there!

  • Welcome to Life Noggin.

  • If you've flown on an airplane, you probably remember the safety briefing before takeoff.

  • This might make flying seem kind of scary, but put your fears aside.

  • You're actually pretty safe up there.

  • There are less than two accidents for every MILLION commercial flights.

  • And even if you happen to be in one, you'll probably survive.

  • Of the over 40 million passenger and cargo flights in 2016, only 10 had deadly accidents.

  • In the United States, it's much more dangerous to be in a motor vehicle, where the odds of

  • dying from an accident are 1 in 114.

  • Airplanes are built to be really secure.

  • Before a new aircraft ever leaves the ground, manufacturers put the model through tons of

  • tests that look at things like extreme heat and cold, high winds, excess water, ice, and

  • lightning strikes.

  • They even launch dead birds into engines to make sure the plane will stay intact if it

  • accidentally hits a flock. Yeah, that's pretty extreme.

  • The rigorous testing also includes the wings.

  • You may have seen airplane wings bending up and down during turbulence.

  • And that's fact, they're made to do that!

  • If the wings were completely rigid, they would break during rough air.

  • Instead, they bend a little to take the force. No, not that kind of force. Different force.

  • The Federal Aviation Administration in the US requires that wings be able to handle at

  • least 1.5 times the maximum load they would experience on a flight.

  • Some can even bend close to 90 degrees without breaking!

  • Just like the outside of the plane, the inside is built for safety.

  • Your seat might be uncomfortable, but it could also save your life.

  • Each seat can take up to 16 g of force.

  • It's also made of flame-retardant materials, as are the walls and carpets.

  • If an accident does happen, aircraft are designed to be evacuated quickly.

  • Ever wonder why they dim the cabin lights for takeoff and landing at night?

  • It might help you fall asleep, but the real purpose is to get your eyes used to the dark

  • in case the power goes out or there's smoke.

  • And if smoke blocks the overhead lights, there are lights on the floor that will guide you

  • to the exits.

  • There's also a reason your seat has to be upright for takeoff and landing.

  • An upright seat locks into position and can handle more force, whereas a reclined seat

  • can thrust forward, causing you injuries.

  • Plus, keeping your seat reclined is dangerous for the people behind you, who won't be

  • able to get out quickly or brace themselves.

  • And bracing for impact can mean the difference between surviving and not.

  • Although every accident is different, the best position for most people is to bend forward,

  • seat belt fastened with your feet on the floor and your arms between your head and the seat

  • in front of you.

  • This will keep your head from snapping forward into the next seat.

  • It might also make a difference which seat you're sitting in.

  • Two studies found that people sitting near the rear of the plane were a bit more likely

  • to survive a deadly crash.

  • But this isn't true in every case, and there's no place where you'll be completely safe.

  • The best way to protect yourself is to listen to the crew and follow all safety instructions.

  • Do you love to fly?

  • Or are you still a little scared? Do you have any scary flight stories you'd like to share in the comment.

  • Let me know down below. So you're likely going to survive your next flight. Phew!

  • But have you wondered if you could survive 2.5 million years ago? Check out this video.

  • During the peak periods where most of the water on Earth was iced,

  • the global average temperatures were 5 to 10 degrees Celsius colder than they are today.

  • This was a much cooler and drier Earth. My name is Blocko. This has been Life Noggin.

  • Don't forget to keep on thinking!
