  • Imagine: you're flying! Weee!!! But wait, where's the plane? A wingsuit? Parachute?

  • Anything! Uh-oh, looks like you're 6 miles (10 km) high and free-falling! So, is this

  • it or is there a way to hack yourself out of this dire situation?

  • Now, don't get me wrong. I'm a sucker for a good life hack. But let's be real:

  • a person's chances of survival when falling from a height of 35,000 feet (10,000 m) are

  • slim. By the way, why do slim chance and fat chance mean the same thing? Anyway, despite

  • this poor outlook, you still have a glimmer of hope! You'll be surprised to know that

  • if you were to stumble from the top of a tall building, you'd be in a much worse situation!

  • (But more on that here in a bit!) To make you feel a little better about your odds,

  • you can take a look at historian Jim Hamilton's book Long-Fall Survival: Analysis of the Collected

  • Accounts. It lists over 200 cases of people falling from a plane without a parachute and

  • living to tell the tale!

  • But you can check that out once you're safe and sound back on the ground. For now, let's

  • get back to your strictly hypothetical free-fall. Right from the get-go, you'd probably pass

  • out because there's not much oxygen when you're 6 miles (10 km) up in the atmosphere.

  • While your brain is on an oxygen-deprived sleep-mode, you'll be falling like a sack

  • of potatoes for about a mile (~1.5 km). See you when you come out of it!

  • While you're unconscious, here's an interesting tidbit about free-falling. Earth's gravity

  • is pulling you down and trying to accelerate you. On the other hand, like any moving object,

  • you're facing air resistance, which is kind of a drag. No really, this drag is increasing

  • the faster you fall. At a certain point (usually within the first third of a mile, or roughly

  • 1,800 feet (550 m)), these two forces become equal and acceleration ceases. It's called

  • terminal velocity -- you're falling at a constant speed of about 120 miles per hour

  • (190 kph), give or take depending on your weight, height, and the density of the air

  • around you.

  • And guess what? If you were falling from a skyscraper, you'd land with the same force

  • as when you fall from a 6-mile height. But you'd only have 12 seconds to prepare for

  • contact, versus having approximately 3 minutes when falling from a plane. It doesn't sound

  • like much, but it makes a world of a difference when it comes to your chances of survival!

  • Ok, your brain is now getting enough oxygen, and you wake up from your mid-fall nap. Welcome

  • back! So, there are 2 scenarios when you're falling from a plane with no parachute. The

  • first is when you're free-falling with just yourself and the clothes on your back. The

  • second way is to try and become a “wreckage rider.” This is what Jim Hamilton calls

  • the lucky ones who've managed to grab some wreckage of the plane and basically surf down

  • to the ground on it. If you can do this, you'll double (or even triple) your chances of survival.

  • And that's been proven by statistics: since the 1940s, there've been 31 wreckage riders

  • who survived and only 13 of those who had to totally free-fall empty-handed.

  • In 1972, Serbian flight attendant Vesna Vulović incidentally broke a world record for surviving

  • the highest fall without a parachute. At 33,000 feet (10,000 m) in the air, the plane she

  • was on exploded, and she fell that whole distance while being squeezed between her seat and

  • a food trolley. She landed on a snowy mountain slope and slid down it until she finally came

  • to a stop. Vulović did receive some serious injuries, but after several months in the

  • hospital, she managed to recover.

  • But let's say you don't find any wreckage to ride down on. Stay calm, it's not over

  • yet! Here's another story to cheer you up. In 1943, American military pilot Alan Magee

  • survived a 20,000-foot (6,000 m) absolute free-fall that ended with him crashing through

  • the glass ceiling of the St. Nazaire train station in France. He made it out alive and

  • lived to the age of 82!

  • Ok, now that you can breathe normally and have 2 minutes before you land, you can enjoy

  • the view! And, you can move your body too. Sure, without a wingsuit, you won't be able

  • to gracefully glide down like a flying squirrel, but you can use your legs and arms to steer

  • yourself toward a safer surface, which is

  • Not water! When you're falling at 120 mph (190 kph) from 6 miles (10 km) high, water

  • will feel like concrete. It's good only if the body of water is deep enough and you manage

  • to protect your head from the impact. But if you've got no choice and there's nothing

  • but water below, try to dive. Some say it's best to go feet-first with your legs straight

  • and pulled tightly together (that's key!). Others swear you need to dive head-first with

  • your arms stretched above you and your fingers laced togetherthis will protect your

  • head from the impact. Whatever you choose (or end up having to settle for), vertical

  • is best when it comes to deep water landings.

  • Ok, if water isn't the best option (or one at all), then what? Look for something that

  • can soften the blow – a snow bank or slope, a haystack, a big tree. Marshland is ideal

  • since it's soft and swampy. Just watch out for the gators afterward. If there's a town

  • or village below, look for something big and flatsay, a truck or camper. A tile or

  • glassy roof is much better than a concrete one. Remember Alan Magee's glass-roof landing!

  • Now that you've chosen your target, you need to try and direct your fall. To slow

  • down, spread your arms and legs apart (think flying squirrel!), throw your head back, and

  • straighten your shoulders. The goal is to make your body take up as much space as possible

  • because it'll create more resistance so that you can maneuver your body and direction

  • more easily.

  • To steer right, lower your right shoulder and look to the right. The same goes for banking

  • left to go left. If you need to go forward, you'll straighten your legs and arms while

  • sweeping them back along your sides. To make your body move backward, straighten your arms

  • out in front of you, and bend your knees. These are familiar movements to those of us

  • who've tried skydiving before. Yeah, it's fun.

  • Buuut you're not skydiving in this scenario. Just remember that no matter what the surface

  • below is, you need to avoid landing on your head. Brain injuries are no joke, and it'll

  • immediately set your chances of survival to zero. If you're falling with your head down

  • and can do nothing about it, try to land on your face. I know, it sounds counter-intuitive,

  • but it's better than hitting the top or back of your skull.

  • Now, right before landing, you have two more choices depending on who you ask. You can

  • either maintain that spread-eagle pose or pull your legs together and keep your knees

  • and hips tight. You better decide fastyour 3 minutes are up!

  • Boom! Congratulations, lucky you -- you're alive! You look like a pancake but you're

  • breathing. You survived-- What are you gonna do now? I'm going to WallyWorld! No really,

  • if you've landed in the jungle, I've got one more story of survival that should be

  • of use to you

  • It was Christmas Eve in 1971, and 17-year-old Juliane Koepcke was flying from Lima to Pucallpa,

  • Peru right after celebrating her high school graduation. When her plane came up on some

  • severe weather and was struck by lightning, the whole thing exploded right above the Amazon

  • Rainforest. After falling over 10,000 feet (3,000 m), Koepcke, still strapped into her

  • seat, hit the ground and passed out.

  • When she came to the next morning, she found herself all alone in the jungle. She was pretty

  • beaten up, but she could walk, and that's exactly what she did. So, how on Earth could

  • this teen survive 11 days stranded in the middle of the Amazon? Well, maybe she was

  • lucky in that she had a unique set of skills for a girl her age. Juliane's parents were

  • both scientists: her father was a biologist, and her mom - an ornithologist. They used

  • to take their daughter with them to a research station deep in the jungle. So, she knew about

  • all the possible dangers and how to avoid them.

  • She walked very slowly, feeling the ground with a stick so that a venomous snake wouldn't

  • surprise her. She had no fire or warm clothes, drank rainwater, and had only some candies

  • for food. She was too weak to try to catch fish or hunt, but she just kept walking along

  • the river. Her dad always taught her: when you're lost, follow the river downstream

  • to civilization. (Keep that in mind if you ever find yourself in a similar situation!)

  • On the 10th day, she came across a small hut. Already exhausted, she decided to rest there

  • for the night. In the morning, some fishermen found her in their shelter and took Juliane

  • to the nearest village, where she was taken by helicopter to Pucallpa. The girl survived

  • not only because she was lucky but also brave and smart: she left the place of the accident

  • and kept going!

  • Anyway, I hope you won't ever have to put these tips to the test. But, hey, if the topic

  • ever comes up in conversation, now you know how to survive a 35,000-foot (10,000 m) free-fall!

  • Me, well years ago when I used to skydive and was traveling somewhere on an airline,

  • I would always bring my parachute in the cabin with me. It was fun to provoke some wide-eyed

  • looks from the other passengers. I'd simply say: I guess you haven't flown this airline

  • recently, have you? and walk right on past. True story.

  • Do you know any other tips on what to do in an extreme situation? Please share them down

  • in the comments! And if you learned something new today, then give this video a like and

  • share it with a friend. Buthey! – don't bail out just yet!

  • We have over 2,000 cool videos for you to check out. All you have to do is pick the
