Can you survive a 10000 foot fall?
A full 42 of those falls occurred at heights over 10,000 feet (above 3,000 meters), such as the tale of 17 year old Juliane Koepcke who not only survived an approximately 10,000 foot free fall, but also a subsequent 10 day trek alone through the Peruvian rain forest with no real supplies other than a little bag of …
How long does it take to fall 1000 feet?
It takes very roughly 10 seconds to fall the first 1,000 feet and then about 5 seconds for every subsequent 1,000 feet – so if an experienced skydiver falls for about 10,000 feet before deploying their parachute they will have had roughly 60 seconds of freefall.
What is the Best Way to Survive Falling Out of a Plane with No Parachute?
It takes about 10 seconds to drop the first 1,000 feet, and then about 5 seconds for every additional 1,000 feet – so if an experienced skydiver falls about 10,000 feet before deploying their parachute, they’ve had about 60 seconds of freefall.
Different people fall at slightly different speeds because different sizes and shapes of people create more or less drag. When you fall through the air you create drag and air rushes around your body at high speed. This is called “relative wind” in sport.
Essentially, you feel a lot of wind as you fall through the air at high speed. A less air resistant – more aerodynamic shape (e.g. a small person with a large belly) will generally fall faster than a person of similar mass – but who is tall and has long arms and legs. As you become a more experienced skydiver, you will learn how to change your rate of descent by making changes to your body position. By changing your posture, you affect your air resistance and therefore your rate of fall. It is a common myth that all objects fall at the same rate, this rule only applies in absolute vacuum where there is no resistance – here on earth we have air!
Does falling on water hurt?
Falling into water doesn’t provide a softer landing than concrete when falling from such a great height. Terminal velocity for a human is about 120 miles per hour. A skydiver reaches that in about 1,000 feet. Most victims of bridge jumps or falls die of broken necks, not drowning, Kakalios said.
What is the Best Way to Survive Falling Out of a Plane with No Parachute?
How is it possible?
Although there are too many variables for a simple answer, physics explains much of it. Jim Kakalios, a physics professor at the University of Minnesota and author of “The Physics of Superheroes,” says there are two main factors that can make survival more likely: maximizing drag and maximizing the time it takes to get to you to slow down.
“A cable car has the aerodynamics of a brick,” he emphasized. “You have a large amount of potential energy at the top if the cable breaks, and the kinetic energy when you land is where the damage originates. But instead of accelerating (all the energy that goes in), some of the energy goes into the work of pushing the air out of the car’s path. It was similar when the 35W bridge collapsed; the bridge span had to do all this work to push away the air and support structures.
Video of the bridge collapse shows it lasted four seconds.
“That’s twice as long as if it were in a vacuum,” he said.
Another way of thinking about the accident in Switzerland: A cable car is about the size of a small car, Kakalios said. The cable car would have been traveling about 60 miles per hour on impact, he calculates. People survive car crashes of this speed, especially when airbags slow the impact.
“Let’s say the time it takes to slow you down after a collision increases from one millisecond to three milliseconds,” Kakalios said. “It’s still very fast, but it’s three times as long, so hit with a force three times smaller – a force that would have killed you won’t do it now.”
This is likely what happened to the baby in the cable car: the crash killed the baby’s parents, but the baby was cushioned by a backpack – and probably the parents’ bodies. Adults generally have a better chance of surviving a fall because a larger body can withstand more force.
Kevin Hines, who attempted suicide by jumping off the Golden Gate Bridge in 2000, believes the position in which he entered the water — as if to sit down — helped him survive.
“But even if there is an optimal way, and even if you can get yourself into that position during a fall, an inch adjustment one way or the other could disrupt the (landing) and create the trauma that would crush your body. said Charlie Euchner, a cases writer at Yale University who was researching a book about jumping off the Golden Gate Bridge.
A fall into water offers no softer landing than concrete when falling from such a great height. The top speed for a human is about 120 miles per hour. A skydiver can do that in about 1,000 feet.
Most victims of bridge jumps or falls die from broken necks rather than drowning, Kakalios said.
“You go so fast that the water doesn’t have time to get out of the way and it resists you when you try to get in,” he said.
Also, there is the issue of water temperature and reaching the water surface if you survive the jump.
Several factors allowed Hines to survive: after his perfect landing, Hines believed a bottlenose dolphin was keeping him afloat until the Coast Guard swooped by and rescued him.
Hines, who says he decided he wanted to live the second his hands left the railing, is now married, happy and fit, Euchner said.
“It’s a story with a happy ending,” Euchner said. Still, the reasons for this happy ending are unclear, as they are in most cases of survival.
“At the end of the day, researchers were still saying, ‘Who the hell knows?’ He was lucky,” said Euchner.
Is jumping into water from high altitude fatal?
At extreme velocities, accelerating your body’s mass of water will kill you anyway. However, what actually kills you is hitting the surface.
What is the Best Way to Survive Falling Out of a Plane with No Parachute?
If you were to go into the water, you would have to “get the water out of the way”. Suppose you need to get 50 liters of water out of the way. In no time you have to move this water a few centimeters. This means that the water only has to be accelerated in this short time, and if you accelerate 50 kg of matter with your own body in this very short time, your body will deform, regardless of whether the matter is solid, liquid or gaseous.
The interesting part is, it doesn’t matter how you enter the water – it doesn’t really matter (in terms of death) what position you enter the water in at high speed. And you will slow down your speed in the water, but too fast for your body to keep up with the forces from different parts of your body slowing down at different times.
Basically I make a very rough guess as to whether it would kill just considering one factor, that the water needs to be moved away. And conclude it will still kill, so I’m not even trying to come up with all the other ways it would kill.
Update – revised:
One of the effects omitted from the estimate is surface tension.
It doesn’t seem to cause any relevant part of the forces – the contribution is there but negligibly small. That depends on the size of the object that comes into the water – it would be different for a small object.
(see answers from how much of the forces involved in penetrating water is related to surface tension?)
At what height does water feel like cement?
The water is like concrete at a height of around 100 meters or 300 feet. You may die in a split second because the water’s surface tension is so strong.

Humans, rocks, and Fabergé eggs all react more fluidly when subjected to high-speed collisions than solid substances (like water) would. More energy in a collision means less importance for binding energy (the energy required to separate two objects).
The hand-waved rule of thumb is that when a material’s random kinetic energy exceeds its binding energy, it behaves as a liquid. With a little more force, it falls apart.
On a much smaller scale, this is also reflected in the results. For example, ice and water differ in that ice has a higher binding energy between its molecules, but water has a higher “heat” kinetic energy. Therefore, when you fall to the ground and splash into the water, a tremendous amount of kinetic energy is released.
The water will continue to behave like water, but since the kinetic energy in different areas of your body is greater than the binding energy holding them together, the body as a whole will function more like a fluid. In other words, it will “spray” (in the broadest sense).
Liquids are much easier to work with because they don’t require as much energy to break down into smaller pieces as solids. However, there is a significant difference in the amount of energy required to break down solids into sawdust.
Although there are many different types of binding energy (molecular, structural, etc.), they all do the same thing: bind atoms together.
This attribute is quickly taught by fluid dynamicists using a number known as the Reynolds number. At higher levels, the liquid becomes “sluggish” (water-like), while at lower levels, it becomes “more viscous” (honey-like).
Does the water feel like concrete?
From any height, water doesn’t feel like concrete. Depending on the height of the fall and your posture at the entrance, the water can seriously injure you or even kill you, but the damage you sustain is much less than that caused by the concrete.
Landing on water reduces the risk of life-threatening injury. A fall onto concrete can easily fracture the skull, but not into water. This can cause you to lose your footing and go down with the ship.
Lack of buoyancy, exposure to cold or choppy water, or distance from shore can result in drowning even if no injuries are sustained. If a person falls into water in an accident, the survival rate is not significantly better than if the person falls onto solid ground.
Does hitting water feel like hitting concrete?
Yes, hitting water feels like hitting concrete. It is true that water becomes more solid at high speeds due to pressures created by breaking through the surface; At extreme speeds it really is like hitting concrete!
You’d die just as quickly if you hit water at the bottom of a 1,000-foot drop instead of a solid object. If you had a parachute and you fell from 10,000 feet to 9,000 feet you would certainly survive.
When you enter a body of water, you have to use some force to get it out of the way… When a boat hits the water fast, there’s a lot of drag. Bones and internal organs can be damaged by great forces. It does to you.
Most of the time it’s not too far. A fall from a height of 6 to 8 meters is generally safe, but anything above that is very dangerous. To complete a 90-meter climb, she first went up alone.
If limbs are injured or loss of consciousness, landing in the water will cause breathing and swimming problems.
Why does the water feel hard when falling from a great height?
Continue reading the article to learn why the water feels hard when falling from a great height.
First, why should the water be affected by your actions? You will be the one who staggers. If you’re about to collapse, you’ve got a lot of energy stored up. Potential energy is converted to kinetic energy once you start falling.
Due to Earth’s gravity, your speed will steadily increase until it reaches terminal speed. When mass, surface area, and wind resistance are factored into an object’s descent, terminal velocity is the fastest it can possibly achieve.
As a result, the air counteracts and hinders your descent. Think how much more viscous and dense the air would be (thicker). Because it’s thicker, how much harder would it be to move through?
To answer your initial question, when you fall from a great height, the water gets “hard”. Surface tension is a term we use to describe this phenomenon. Many things happen at the same time when you come in contact with the water.
If you free fall the same distance in water instead of in air, you’ll come into contact with denser materials much faster, which is why it’s dangerous. Their speed is reduced by the rapid encounter with the higher density.
But something else is even more important: the surface tension of water ensures that it resists the force your body exerts on it. When it comes to water molecules, they are more attracted to each other than to air molecules.
Water has almost little interaction with the air molecules, which are almost exclusively diatomic. This is because the O’s in H2O are slightly more negative and the H’s are slightly more positive, resulting in positive hydrogens being attracted to the negative oxygens, all in different water molecules.
That’s all well and good, but it doesn’t explain why a 10 ton steel plate would cut right through the water if you and I hit it like a steel wall? Surface area and kinetic energy both affect surface tension.
These weak interactions between water molecules can be broken depending on how hard you hit the water and how much surface area you use. As the surface area increases, so does the amount of kinetic energy needed to break the surface tension.
So, remember the concept of “terminal velocity”? Surely that has something to do with volume and area? The final speed decreases with increasing surface area.
Due to the fact that they break the weak bonds of so few water molecules, objects with a small surface area in the X-Y plane can have very high terminal velocities and so penetrate surface tension much more easily.
It is impossible for an object with a large surface area to move fast enough to generate a surface tension reaction force.
In contrast, objects just big enough to have a high terminal velocity but too small to break surface tension experience the surface tension reaction force equal to the force created by the kinetic energy they have , on which water is applied.
Conclusion
It is true that water becomes more solid at high speeds due to pressures created by breaking through the surface; At extreme speeds it really is like hitting concrete!
It feels like hitting concrete when hitting water from a great height, but it’s not the same as hitting concrete from the same height. Although the value exceeds 6 kN, impact with the water surface can be fatal, even if it is less than impact with concrete.

How do you jump off a cliff into water?
- Never go cliff jumping alone.
- Make sure the water is deep enough.
- You may experience some intense water pressure depending on the depth.
- Wear sneakers or water shoes.
- Keep your body tight and streamline when you jump.
- Blow out through your nose.
- Be of sound mind.
- Confidence is key.
What is the Best Way to Survive Falling Out of a Plane with No Parachute?
Everyone, whether beginner or expert, should be prepared before diving and be able to assess their surroundings. With that in mind, here are ten essential tips for safe cliff diving.
1. Before you even think about jumping off a cliff, you must be an experienced swimmer.
It is non-negotiable to feel comfortable in the water before propelling your body from a raised surface into an ocean, lake or river. Strong swimming skills are required to enter a body of water, breathe properly underwater, and come back to land. There’s a reason this is NUMERO UNO on the list!
2. Never go cliff jumping alone.
Not only is it stupid to jump off a cliff alone, it’s also lonely. When you’re alone, who would be there to take that sick picture of you in mid-air?
3. Make sure the water is deep enough.
Bruises on the feet, compound fractures and paralysis are all potential risks of cliff jumping. However, you can drastically reduce the likelihood of these results by correctly estimating water depth. If the water is less than 4 meters deep, DO NOT jump! You can test the depth with a long stick or wade into the suggested jump site beforehand, but it’s best if you can find an accurate measurement. Also, if there are rocks at the bottom, be aware that they may appear deeper than they actually are.
4. Depending on the depth, there may be strong water pressure.
Remember that once you’ve jumped off the cliff and submerged in water, you may feel pressure, especially in your ears. Don’t panic, just surface calmly and the feeling should dissipate. If you feel unwell for a long period of time, block your nose, take a deep breath, and blow out while keeping your mouth closed.
5. Wear sneakers or water shoes.
To avoid bruising or cutting the soles of your feet, use a pair of sneakers or water shoes when cliff jumping.
6. Don’t jump head first.
Jump feet first when cliff jumping. Unless you’re an expert (and no, being a self-proclaimed expert doesn’t count), you’re putting yourself at serious risk of injury or death if you jump headfirst.
7. Keep your body tight and streamlined when jumping.
Keep your arms and legs in the vehicle at all times… something to consider before jumping off the edge. Thrashing arms and legs could hit nearby objects or throw you off balance.
8. Blow out through your nose.
When you hit the water, remember to breathe out through your nose. This will prevent water from going through your nose and help equalize the water pressure in your head.
9. Be sane.
Drinking and cliff jumping is irresponsible. If your judgment is impaired in any way while participating in this ALREADY RISKY activity, just be reckless with your own life. Don’t be stupid and enjoy the Brewski after you’ve managed a few good jumps.
10. Trust is key.
You have to be 100% sure that you want to jump off that cliff. If you have an ounce of doubt in your head, it could spell disaster for your jump. You want your body to be calm and in control before, during and after your jump.
What is the highest free fall survived?
The explosion and crash killed everyone on board. Everyone except Vesna, who survived a fall of 33,333 feet (10,160 metres; 6.31 miles). 50 years on, this remains the highest fall survived without a parachute ever. JAT Flight 367 had two scheduled stopovers in between Stockholm and Belgrade.
What is the Best Way to Survive Falling Out of a Plane with No Parachute?
The flight path between Stockholm in Sweden and Belgrade in Serbia took the plane over Czechoslovakia – now the Czech Republic – and there the plane exploded in three pieces.
The explosion and crash killed everyone on board. All except Vesna, who survived a fall from 33,333 feet (10,160 meters; 6.31 miles).
50 years later, this remains the highest fall ever survived without a parachute.
JAT Flight 367 had two scheduled stops between Stockholm and Belgrade. First was Copenhagen in Denmark, where the secondary cabin crew – including Vesna – boarded the plane. They never made the second stop in Zagreb, Croatia.
As fate would have it, Vesna wasn’t actually supposed to be working on Flight 367, as she revealed in a 2002 interview with Green Light. However, the airline had confused her with another stewardess with the same first name, so the plane left Denmark with 23-year-old Vesna Vulović on board.
At 4:01 p.m., 46 minutes after takeoff, an explosion in the luggage compartment ripped the McDonnell Douglas DC-9 aircraft into three pieces.
As the cabin depressurized, the passengers and other flight crew were believed to have been sucked out of the plane into freezing temperatures and fell to their deaths.
Vesna’s miraculous survival was attributed to being pinned to the rear end of the fuselage (the main body of the aircraft) by a food truck.
The fuselage detached from the rest of the aircraft and hurtled towards the ground in a wooded area near the Czechoslovakian village of Srbská Kamenice. It landed in the thick snow at a favorable angle, which most likely saved Vesna’s life.
In addition, Vesna’s doctors determined that her low blood pressure caused her to quickly pass out as the cabin depressurized, which prevented her heart from bursting on impact.
Vesna was found screaming in the rubble by Bruno Honke, a villager and former World War II medic who was able to provide vital first aid before rescuers arrived.
Although Vesna survived, she sustained severe injuries and spent the following days in a coma. She suffered a fractured skull, two broken legs, three broken vertebrae, a broken pelvis, multiple broken ribs, and temporary paralysis below the waist.
Amazingly, after ten months, Vesna was able to walk again, albeit with a permanent limp due to the twisting of her spine.
She had no memory of the crash or anything from the following month.

In her native country of Yugoslavia, Vesna Vulović became a national icon, honored by Yugoslav President Josip Broz Tito. A song titled “Vesna stjuardesa” (“Vesna the stewardess”) was even written about her by Serbian folk singer Miroslav Ilić.
At the Guinness World Records Hall of Fame ceremony in 1985, Paul McCartney presented Vesna with a certificate and medal for the highest fall survived without a parachute. Vesna and her friends grew up in Yugoslavia listening to the Beatles so this was a very special moment for them.
What Caused the Explosion on JAT Flight 367?
According to the Czechoslovak Civil Aviation Authority, the explosion was caused by a briefcase bomb placed in the aircraft’s luggage compartment.
On the same day as the Flight 367 tragedy, another bomb was detonated on a train between Vienna and Zagreb, injuring six people.
The day after these events, the Swedish newspaper Kvällsposten received a call from a self-proclaimed Croatian nationalist who blamed himself for the crash of Flight 367.
Although no arrests were ever made, Yugoslav authorities suspected that a Croatian ultra-nationalist terrorist group, the Ustasha, was behind both bombings.
A total of 128 terrorist attacks were carried out by Croatian nationalists against Yugoslavia between 1962 and 1982.
The cause of the explosion and subsequent crash of Flight 367 has been the subject of several conspiracy theories over the years, the most popular being that the plane was accidentally shot down by Czechoslovak anti-aircraft missiles at a much lower altitude of 800 meters (2,600 ft).
However, this claim was contradicted by flight data obtained from the aircraft’s flight recorders, which provided accurate data on the aircraft’s altitude, acceleration, direction and speed at the time of the explosion.
Both boxes were analyzed by specialists from Yugoslavia, Czechoslovakia and the Netherlands, who confirmed that the plane had indeed fallen from the stated height of 33,333 feet (10,160 m).
The theory was also rejected by the Civil Aviation Authority and Czech Army experts. There is insufficient evidence against the official crash report to disqualify Vesna’s record.
After recovering from her injuries, Vesna continued to work for JAT Airlines in a desk position, but was fired in the early 1990s for taking part in anti-government protests against Slobodan Milošević, then President of Serbia in Yugoslavia. Milošević was later tried in The Hague for crimes against humanity.
“I’m like a cat, I’ve had nine lives,” she told the New York Times. “But if nationalist forces prevail in this country, my heart will burst.”
Although she died in December 2016 at the age of 66, Vesna Vulović will forever live on as an anti-nationalist heroine.
While her death-defying story continues to fascinate people around the world, she will also live on as a symbol of survival against all odds.
While we always love to see records broken, this is an exception and we hope no one ever experiences a fall like Vesna’s again.
Why don’t they put parachutes on planes?
Short answer: There are a few reasons, including the lack of parachute training of passengers, high speed of the airplane, cold temperatures at that altitude, non-conducive design of commercial planes and the cost spike, which make putting parachutes onboard commercial airplanes unviable.

What happens if you jump into water from a great height?
The ocean surface is not as hard as the ground but if you drop from a plane, you would hit it with such a high velocity that the pressure would most likely kill you or cause very serious damage. Considering air resistance, the terminal velocity of a human, right before reaching the water, would be at most some 150 m/s.

Can you break bones jumping into water?
If you jump from 20 feet (6 meters) above the water, you’ll hit the water at 25 mph (40 kph) — the impact is strong enough to compress your spine, break bones or give you a concussion [source: Glen Canyon Natural History Association].
What is the Best Way to Survive Falling Out of a Plane with No Parachute?
Cliff jumping from any height cannot be called safe – it is one of the most dangerous extreme sports. In fact, official tourism websites of popular cliff jumping destinations do not advertise this activity.
Cliff jumping puts a tremendous strain on your body. When you leap 20 feet above the water, you hit the water at 25 mph—the impact is strong enough to compress your spine, fracture bones, or give you a concussion [source: Glen Canyon Natural History Association ]. But that’s only if you step in feet first in a straight, vertical line – a horizontal or “pancake” landing is like hitting concrete. Halving the jump height to 3 meters as mentioned reduces your impact speed to 27 km/h and even cars will take damage if hit at that speed.

Because of the high risk of injury, the World High Diving Federation recommends that no one dive from depths of 20 meters (65.5 feet) or deeper unless professional rescue divers are stationed in the water [source: World High Diving Federation]. Contusions, dislocated joints, broken bones, compressed spines, injured discs, paralysis and death are among the injuries suffered by cliff divers.
Competitive cliff divers dive from heights of 59 to 85 feet (18-26 meters), but professional show divers in Acapulco, the La Quebrada Cliff Divers, sometimes jump from 148 feet (45 meters) above the water [sources: World High Dive Federation , Red Bull Media Service, vacation made easy]. These show divers survive to dive another day because they have trained for years, are familiar with the area and adapt their dives to changing wave and water conditions. But they also occasionally get injured.
The WHDF considers water depths of 43 to 49 feet (13 to 15 meters) adequate for dives from 65 feet (20 meters) or shallower, but water clarity is also a critical factor in cliff diving safety. Hitting the water from a great height can cause injury, but hitting something in the water—a rock, branch, the bottom, even a fish—or the bottom of the body of water can be fatal. Choppy water and high waves often obscure the water surface and affect the precision of the entry, but world champion cliff jumper Orlando Duque says waves break the water surface and soften the impact. Entering the water at the peak of a wave shortens the dive, and any acrobatics must be completed early in the dive so you can position your body for water entry.

Does the water feel like concrete?
From any height, water doesn’t feel like concrete. Depending on the height of the fall and your posture at the entrance, the water can seriously injure you or even kill you, but the damage you sustain is much less than that caused by the concrete.
Landing on water reduces the risk of life-threatening injury. A fall onto concrete can easily fracture the skull, but not into water. This can cause you to lose your footing and go down with the ship.
Lack of buoyancy, exposure to cold or choppy water, or distance from shore can result in drowning even if no injuries are sustained. If a person falls into water in an accident, the survival rate is not significantly better than if the person falls onto solid ground.
Does hitting water feel like hitting concrete?
Yes, hitting water feels like hitting concrete. It is true that water becomes more solid at high speeds due to pressures created by breaking through the surface; At extreme speeds it really is like hitting concrete!
You’d die just as quickly if you hit water at the bottom of a 1,000-foot drop instead of a solid object. If you had a parachute and you fell from 10,000 feet to 9,000 feet you would certainly survive.
When you enter a body of water, you have to use some force to get it out of the way… When a boat hits the water fast, there’s a lot of drag. Bones and internal organs can be damaged by great forces. It does to you.
Most of the time it’s not too far. A fall from a height of 6 to 8 meters is generally safe, but anything above that is very dangerous. To complete a 90-meter climb, she first went up alone.
If limbs are injured or loss of consciousness, landing in the water will cause breathing and swimming problems.
Why does the water feel hard when falling from a great height?
Continue reading the article to learn why the water feels hard when falling from a great height.
First, why should the water be affected by your actions? You will be the one who staggers. If you’re about to collapse, you’ve got a lot of energy stored up. Potential energy is converted to kinetic energy once you start falling.
Due to Earth’s gravity, your speed will steadily increase until it reaches terminal speed. When mass, surface area, and wind resistance are factored into an object’s descent, terminal velocity is the fastest it can possibly achieve.
As a result, the air counteracts and hinders your descent. Think how much more viscous and dense the air would be (thicker). Because it’s thicker, how much harder would it be to move through?
To answer your initial question, when you fall from a great height, the water gets “hard”. Surface tension is a term we use to describe this phenomenon. Many things happen at the same time when you come in contact with the water.
If you free fall the same distance in water instead of in air, you’ll come into contact with denser materials much faster, which is why it’s dangerous. Their speed is reduced by the rapid encounter with the higher density.
But something else is even more important: the surface tension of water ensures that it resists the force your body exerts on it. When it comes to water molecules, they are more attracted to each other than to air molecules.
Water has almost little interaction with the air molecules, which are almost exclusively diatomic. This is because the O’s in H2O are slightly more negative and the H’s are slightly more positive, resulting in positive hydrogens being attracted to the negative oxygens, all in different water molecules.
That’s all well and good, but it doesn’t explain why a 10 ton steel plate would cut right through the water if you and I hit it like a steel wall? Surface area and kinetic energy both affect surface tension.
These weak interactions between water molecules can be broken depending on how hard you hit the water and how much surface area you use. As the surface area increases, so does the amount of kinetic energy needed to break the surface tension.
So, remember the concept of “terminal velocity”? Surely that has something to do with volume and area? The final speed decreases with increasing surface area.
Due to the fact that they break the weak bonds of so few water molecules, objects with a small surface area in the X-Y plane can have very high terminal velocities and so penetrate surface tension much more easily.
It is impossible for an object with a large surface area to move fast enough to generate a surface tension reaction force.
In contrast, objects just big enough to have a high terminal velocity but too small to break surface tension experience the surface tension reaction force equal to the force created by the kinetic energy they have , on which water is applied.
Conclusion
It is true that water becomes more solid at high speeds due to pressures created by breaking through the surface; At extreme speeds it really is like hitting concrete!
It feels like hitting concrete when hitting water from a great height, but it’s not the same as hitting concrete from the same height. Although the value exceeds 6 kN, impact with the water surface can be fatal, even if it is less than impact with concrete.
Frequently Asked Questions (FAQS): At what level is water like concrete?

How High Can You Fall Into Water
How high can you fall into the water
How high can you fall into the water?
There is no limit to how high you can fall into the water. You’ll probably die if it’s more than 5 stories, but you didn’t say “and live”. They can fall into the water from a height of 24 miles. You will die, but it can happen. But you won’t die wearing a parachute.
How high can someone survive falling into the water?
The upper survivability limits of human tolerance to impact velocity in water appear to be close to 100 ft/sec (68.2 mph) corrected velocity, or the equivalent of a 186 foot free fall.
How high can you jump off a cliff into the water?
Your legs are pressed against your body. If you’re lucky enough to still have air in your lungs and don’t have major body damage, you’ll be about 50-100 feet underwater.
Can you jump into the water with a parachute?
If you can dive in water, it doesn’t feel great at 125 mph, but you’ll survive if the water is deep enough — at least 12 feet or so. Head for the water (helpful if you’ve skydived before and know how to steer as you fall) and dive straight into it.
A man survived a 500-foot fall from a New York skyscraper. When the 35W Bridge collapsed in Minneapolis, 13 people died, but many more survived the more than 100-foot fall.
Is hitting water like hitting concrete?
Pressure caused by breaking the surface makes water appear solid on shorter timescales, which is why it is said that hitting water at high speed is like hitting concrete. In these short times, it really is like concrete!
At what height does jumping into the water feel like concrete?
If you fall into the water from 50 or 100 feet or more, it’s like hitting concrete. The water can’t move away fast enough to cushion your fall, as it can when you jump off a five-foot or ten-foot diving board into a pool.
What is the world record in high diving?
58.8m
1. The highest dive. On August 4, 2015, the Swiss jumper of Brazilian descent Lazaro “Laso” Schaller set the world record in the jump from the platform from a height of 58.8 m (higher than the Tower of Pisa, which is “only” 56.71 m) and a speed from 120 km to /h at its entry into the water.

Jumping into water
$\begingroup$
Answering your questions in reverse order:
Yes, a long, pointed object (like your arms above your head in a nosedive, or your pointed toes in a feet-first entry) makes a big difference. Remember the tongue-in-cheek adage, “It’s not the fall that kills you; it’s the sudden stop?” This is exactly what distinguishes a fall on concrete from a fall into water: How suddenly does the stop come? And making that stop LESS abruptly (reducing the amount of deceleration during the stop) is exactly how airbags save your life in a car accident. One can decrease the amount of delay by decreasing the ratio $(\Delta V / \Delta t)$. Since there is an approximately linear relationship between time and distance traveled at the moment of impact, you can achieve the same effect by decreasing the ratio $(\Delta V / \Delta s)$, where $s$ = distance traveled during the deceleration event is . The easiest way to do this is to lengthen $s$.
One thing to remember about waterfall stats is that a large number of them are likely to be “untrained”. These are not Olympic divers working to 250 feet. A large proportion of them are unconditioned people who are forced to “escape” into the water; or, even worse, people TRY to die.
Assuming you’re doing the right thing and optimizing your form for water entry, while minimizing your wind resistance during the fall:
1.) A 30 foot fall results in a speed of approximately 44 ft/s = 30 mph.
2.) A 100 foot fall results in a speed of approximately 80 ft/s = 54 mph.
3.) A fall from 150 feet results in a speed of approximately 97 ft/s = 66 mph.
4.) A fall from 250 feet results in a speed of approximately 125 ft/s = 85 mph.
The first case is a high dive I did for the Navy, and it’s trivial for anyone who’s HWP and doesn’t do a belly flop. The second is an approximation of a jump from a carrier deck, which the high dive should teach survival (being able to swim after falling). The third is only 20% faster entry speed (and power) and should be survived by anyone in good shape and able to execute good form (pointy toe entry, locked knees, head up, arms straight up). The cliff divers of La Quebrada routinely dive from 125 feet as a tourist attraction. If forced to choose, I would choose a feet first entry at 150 feet over a dive at 125.
So the interesting part is the distance from 150 to 250 feet. My guess is that for someone willing to voluntarily perform repeated water jumps/jumps from a height of $x$ $x$ will be somewhere around $225 \text{ feet} \pm 25 \text{ feet}$ .
EDIT: There are documented cases of people surviving falls from thousands of feet (failed parachute) onto LAND. These crazy cases of surviving terminal velocity falls don’t really answer the question; but they are there. For example, Vesna Vulović is the world record holder for the largest surviving fall without a parachute.
What is the Best Way to Survive Falling Out of a Plane with No Parachute?
Peter E. asks: What could I do in free fall after falling out of an airplane to maximize my chances of survival?
Between 1940 and 2008, 157 people fell from planes in a crash without a parachute and survived to tell the story, according to the Aircraft Crashs Record Office in Geneva. A total of 42 of those falls occurred at altitudes greater than 10,000 feet (over 3,000 meters), like the story of 17-year-old Juliane Koepcke, who not only survived a freefall from around 10,000 feet, but also a subsequent 10-day hike through the Peruvian rainforest with no real supplies other than a small bag of candy.
Well, while you might think this could never happen to you, turns out whether you’re falling from 30,000 feet or much more commonly 30, the same basic strategies apply. And for reference here, about 30 feet or about 9 meters is about the height at which you’re more likely to die from your injuries than survive. At altitudes of only about 80 feet, only about 1 in 10 people survive and pretty much everything goes to hell from there.
So what can you do to increase your chances of survival if you ever make your best impression of Icarus?
First of all, if you’re going to drop to earth at altitudes above about 1,500 feet, the higher you are the better, at least up to a point. You see, at just 1,500 feet you hit your terminal velocity before you hit the ground, which is roughly 120-140 mph for a typical adult human doing his best to fall as slowly as possible. The problem for you is that if you start your fall at about 1,500 feet, you only have about 10-12 seconds before you splash. Not much time to do anything useful.
On the other hand, if you fall from, say, 30,000 feet, you first have to endure extremely uncomfortable stadium temperatures of -40 C/F and air currents that make it all the more chilly. You may also briefly lose consciousness from lack of oxygen. why is this better Well, on the one hand, if you never regain consciousness, at least you’ll be spared the horrific minutes of the fall. But in most cases, you will probably regain consciousness after about 1-2 minutes to implement your survival plan.
Sure, you’re probably going to die anyway, but, hey, doing anything will distract you from the truth that your adventure here on earth is about to end and, no matter who you are, from the fact that you ever existed, will soon be forgotten – for most in a frighteningly short time …
But don’t go gently into this good night, my friends. Anger, anger against the dying of the light.
So initially, to give you maximum time to execute a plan and reduce your speed as much as possible, start by sprawling in the classic X/W Skydiving Pose, belly down. This is shockingly effective at slowing you down. For example, it turns out that in the most streamlined instances of freefall, it’s actually possible to reach speeds well in excess of double the aforementioned 120 mph, which is more typical in that X pose.
There’s a way to slow down significantly more, but it’s not time to try that trick just yet. Once in position, your first priority is to look for an object to hold on to – bonus points if the object falls slower than you. It turns out that so-called “wreckage riders” are about twice as likely to survive such a fall as those who have nothing to hold on to except the knowledge that they’ve wasted so much of their lives worrying doing and looking for things that don’t really matter and can’t do anything about it now.
Why Wreck Riders have such a significantly higher survivability rate is not only because the object can slow terminal velocity down a bit in some cases, but it can also potentially be used as a buffer between them and the ground.
As Professor Ulf Björnstig from the University of Umeå found, at speeds around the terminal speed for humans, you actually only need about half a meter to slow down in order to survive, at least in theory. Every extra inch beyond that counts significantly to increase your chances.
With that in mind, don’t be afraid to think outside the box on this one – just as having someone by your side can potentially be a huge benefit when you’re being chased by a bear (almost certain death in an almost safe to change). survivability if you’re a faster runner than that person), in free fall, the body of another passenger who is also about to say goodbye to the world and be instantly forgotten is also a huge benefit – in this case, by placing that person between you and the ground before touching him. Bonus survival points if you find a morbidly obese person. Sure, top speed will be a little higher in a case like this, but that extra padding will go a long way.
Just make sure the other passenger doesn’t have the same idea.
Pro tip to avoid spending your final moments pedaling through the air trying to elbow a person out of low orbit – go in as if you’re about to hug them lovingly; to throw this mortal shell into the arms of another. As if to say everything will be fine, we’re in this together. Then, just before touching the ground, turn quickly to have her body beneath you. You’ll never see it coming.
And don’t underestimate the power of a group hug that forms in this scenario. All those soft, soft bodies you have to put between you and the ground…
On the other hand, if for some weird reason you want to be selfless and say save your kid or something, a few parents stacked with the kid on top would not only give the kid the best chance of survival, but maybe even a really decent one, since kids, especially under 4 years old, are significantly more likely to survive falls from any height anyway, let alone if you give them a nice thick puffer from two bodies that have also been through a lot eating delicious KFC for much of their lives.
Whether you manage to find a wreck or another human to drive all the way down, you want to do your best to aim for the softest thing you can see. The goal per se does not have to be that close. For those who know what they’re doing, it’s possible to cover horizontal distances of up to a mile for every mile they fall without special equipment. It turns out that this way you can shave another 20-40mph off your decent speed through so-called tracking – essentially by positioning your body to gain speed as you fall in a horizontal direction. for a good tracker that can achieve horizontal speeds roughly equal to their vertical speed.
Unfortunately, there’s no exact consensus on what’s the best position for tracking with maximum efficiency, since different body types react differently and the like, but the general method is to straighten your legs rather than bend and bring them together. At the same time, bring your arms to your sides with your palms down, and then make your body fairly flat with your head angled slightly lower than your feet.
Of course, someone who has no experience maneuvering around in free fall will do a poor job when it comes to actually doing so, let alone eventually managing to hit even a giant target. And as for the benefits of slowing down the vertical descent rate a bit in favor of increasing the horizontal one, it’s not really clear if it would be worth it in the vast majority of cases. For example, imagine jumping out of a car that is going at 100 miles per hour and how that would work for you. Now add in a drop at around 100mph…you’re going to have a bad time.
Aiming at a soft target is definitely valuable. So if you find yourself falling towards Earth, make a mental note to get past you and eventually practice freefall maneuvering.
Fast forward what are the best soft things to try to hit? Well, if you look at the records of people who have managed to survive such falls, deep snow is almost always the best choice, if there is any.
For example, consider the case of British sniper Nick Alkemade. When his plane crashed in 1944, he decided to jump out of his burning plane, even though the tiny, insignificant detail of his parachute had been rendered unusable before he jumped. While you might think his subsequent fall from over 18,000 feet would surely be his end, thanks to the magic of tree branches and deep snow, his most significant injury was actually just a sprained leg, though he was quickly captured by the Germans. More impressed by his near-death experience than his nationality, they released him a few months later and gave him a certificate commemorating his fall and subsequent survival.
Snow also has the great benefit that since it’s pretty much everywhere, you don’t really need to know what you’re doing to hit it.
Well, if it’s not the dead of winter but one of the other seasons, a freshly tilled field or one with extremely dense vegetation is probably your next best bet – both offer at least some lag buffer while also giving you a big target to aim for, you see quite high in the sky.
For example, in 2015, veteran of over 2,500 skydives, Victoria Cilliers, managed to survive a fall from about 4,000 feet by landing in a freshly plowed field. Granted, she suffered broken ribs, hips, and some vertebrae in her back, but she survived. As for her husband, who had intentionally tampered with both her main parachute and reserve chute so they weren’t working properly (and previously tried to kill her by causing a gas leak in her house), well, he had to move out of her house and to jail.
As far as vegetation goes, even thorny brambles are better than nothing, although any chance of actually hitting and hitting them is likely slim. But whatever the value, in 2006 professional skydiver Michael Holmes managed to do just that, albeit not on purpose, when both his main and backup chutes failed to deploy properly. In his case, he suffered a concussion, a broken ankle and a number of minor injuries, but was otherwise fine.
Now you might be wondering why we didn’t mention water, you might think it’s a good choice as a soft target to hit, and in some ways you can’t go wrong. The problem is that water isn’t exactly smooth at high speed – think belly jumping off a diving board. However, as many extreme cliff divers have demonstrated, water can be far more forgiving than a cement pavement if you hit it right.
The problem is that most people are not very proficient at this type of diving, and even the pros will almost certainly break a lot of bones at top speed, among many other problems. And let’s not even get started on the fact that hitting the water at these speeds can potentially cause the water to shoot up your anal opening with enough force to cause internal bleeding.
Whether that happens or not, even if you miraculously survive, you’re likely to be knocked out or unable to swim properly. So unless David Hasselhoff happens to be around, not a good choice.
Now that you lack something soft to land on or the hope to save you, you want to look for something—anything—to break your fall before you hit the ground. The value of this can be seen in the case of Christine McKenzie, who fell from 11,000 feet in 2004. Shortly before impact, she first hit some live power lines. While you might assume that would have sliced, diced, and fried her, she actually walked away from the whole thing with nothing more than a few broken bones, bumps, and bruises.
A New Jersey native, Alan Magee was about 20,000 feet in 1943 when he decided to jump from his B-17 bomber, which had recently had a partially deflated wing ripped off. Unlike the aforementioned Nick Alkemade, who made a similar decision, Magee actually had a parachute. Unfortunately, he passed out after being thrown from the plane and never used it.
He eventually fell through the glass ceiling of St Nazaire train station in France, slowing him down enough to survive the impact with the stone floor below. Not exactly unscathed, when he was treated he was found to have had a few dozen shrapnel wounds from the previous dogfight, then many broken bones and internal injuries as a result of falling from 20,000 feet. While subsequently captured, he did well and lived to be a whopping 84 years old, dying in late 2003.
As another example of an overhead shooter, we have the 2009 case of cinematographer Paul Lewis, whose main parachute failed during a nosedive. At that point, he clipped it and deployed his reserve parachute…which also failed, resulting in his descent being only slightly slowed. He landed on the roof of an airplane hangar after falling about 10,000 feet. Not only did he survive the incident, his only major immediate injury was his neck, though he appears to have made a full recovery.
Based on the limited data available, a densely forested forest appears to be a better choice to slow your fall than power lines and rooftops. Not only is this easier to aim for, while trees can potentially impale you, their branches have saved many free-fallers such as limbs in the past.
That all brings us to the position you should be in when you actually hit the ground. As you might imagine, the dataset we have to work with just isn’t big enough to definitively answer this question, and for some strange reason we randomly drop thousands of people out of airplanes and ask them to try, Landing in different positions over different surface types is not a study that anyone has ever done.
However, we have some clues as to which is best, thanks in part to data collected by the Federal Aviation Agency and countless experiments conducted by NASA that, when not trying, tell the world about its flat nature in the dark and keeping people away from the wall of ice that keeps the oceans inside (yes, there are actually people who believe that) has done its best to figure out what G-forces humans can reasonably survive and how best to survive them at the far end.
So what’s the consensus here? It’s almost universally said that no matter what height you fall from, you should land on the balls of your feet, legs together, all joints flexed at least a little, and then try to fall slightly backwards and sideways (the classic 5-point impact sequence – feet, calf, thighs, buttocks and shoulder). In this recommendation, you should also wrap your arms around your head to protect it and completely relax every muscle in your body so that everything doesn’t tear immediately, rather than using the surprisingly extreme elasticity of your various parts to stretch things over a larger one unit to slow down by time.
Something to keep in mind in some cases, however, is that NASA research suggests that this so-called “eyes down” impact (where the G-forces are such that your eyeballs are pushed down — hence the generally recommended position here) actually maximized their risk of injury and death in their studies of the effects of extreme G-forces on the human body. Instead, their data shows that “eyes in” (meaning G-forces pushing you back into something — think of accelerating in a car where you’re being pushed back into the seat) is the way your body can absorb the most force and survive.
The problem, of course, is that the forces involved in free falling from a great height are in most cases too extreme for your body to survive in that eye position. While you may end up suffering a lot more injury from landing in an upright position, the whole point is to sacrifice your feet, legs and more to try and reduce the ultimate G-forces felt by your organs and of course the force of impact become when your head touches the surface.
That being said, there’s some evidence that it might be better to bend backwards than to the side, provided you can properly protect your head with your arms.
Whether that’s true or not, I suspect there are some scenarios, like landing in super deep powder, where landing face up in a slightly reclined position with your head tucked in and your arms protecting your head might actually be better for similar reasons might be why stuntmen, trapeze artists, daredevils and the like generally choose this reclined position for their soft object landings.
We should probably also mention that if you’re also hitting the ground at horizontal speed, the general recommendation, aside from protecting your head with your arms, is to literally try to roll with it and not fight it in the slightest. Resistance is futile in this case, and attempts in this direction only increase the likelihood that you will be injured and die.

Bonus Fact:
The current world record for surviving a free fall without a parachute is held by one Vesna Vulovic, who managed to survive a fall from approximately 33,330 feet on January 26, 1972. That day, Vulovic was in such a situation after the commercial airline had been blown up mid-flight, believed to be the work of a Croatian nationalist. Anyhow, everyone on board the plane died except for Vulovic, who not only benefited from being an accidental wreck driver, but also from having her wreckage hit some trees and landed on snow on a slope – all best-case scenarios, literally . While she broke many, many bones throughout her body, among a variety of serious injuries, and ended up in a coma for some time, it is noted that when she woke up, pretty much the first thing she did was see a doctor to ask a cigarette. We’re not sure if this makes her a stone cold badass or just someone who really had to think about the severity of her nicotine supplementation.
