How Often Do Parachutes Fail – How do parachutes work? Fair question if you’re about to skydive (or even if you’re just interested in learning the mechanics of skydiving)! After all, if you’re going to put yourself out of a plane and rely on a big ball of fabric, it helps to know the science behind parachutes.
You’ll be relieved to know they’re much more than a random bunch of materials and seams, there’s a fine-tuned design behind it all. How does a parachute work? The simple answer is with the magic of drag and human ingenuity.
How Often Do Parachutes Fail
Gravity pulls us all equally to the earth: whether it’s a stone or a feather, whatever the object, it will have an acceleration of 9.8 m/s² downwards to the earth. In a vacuum without air, you would see a spring and a rock hit the ground at the same time. So, how exactly is it that in the real world the rock hits the ground first? Well, this is where air resistance comes into play. The feather hits the ground after the stone, not because it is lighter, but because the feather catches more air as it falls; the drag on the surface slows it down.

Part of the science behind parachutes is that they make smart use of air resistance. You see, even though it’s invisible, air is made up of gas molecules, and when you move around, they get pushed aside. The more space you take up and the more surface area you have, you get a greater amount of air resistance.
To take advantage of this, parachutes are often made from a lightweight nylon that has been specially treated to be less porous (that is, it doesn’t let as much air through). This allows your open parachute to create more drag and drift slowly and safely towards the ground.
Terminal velocity is a point where there can be no further acceleration. This constant velocity is achieved when gravity is counteracted and balanced by the resistance of the medium an object falls through (such as air).
How does this apply? Your parachute allows you to descend more slowly because it lowers your terminal velocity by increasing drag. Most parachutes are designed to create a large amount of drag and allow you to land at a safe, low speed.
What If My Parachute Fails?
Parachutes today are designed for a myriad of functions. Military operations use a parachute that is dome shaped, provides only basic control and is used by the military for the deployment of paratroopers and equipment. On the other hand, civilian jumpers most often use a rectangular Ram-air parachute, one constructed with a series of tubular cells that inflate as air is forced into each chamber. The result is a semi-rigid, curved aerofoil wing that provides higher performance and increased manoeuvrability.
All equipment for recreational skydivers contains a dual parachute system: a main parachute and a back-up parachute. These two parachutes are packed into a simple backpack-looking device we call the container.
The main parachute is deployed by a miniature chute, known as the pilot chute. At the appropriate height, a jumper will extract the pilot chute from the elastic pouch, where it is safely stored, sewn to the bottom of the container. The pilot chute inflates and creates enough force to extract the main parachute from the canister. The main parachute is designed to fill with air and inflate slowly and efficiently. The reason for the delayed opening is to avoid too much opening shock on the body. Think coming to a slow, steady stop at a red light as opposed to slamming on the breaks.

How To Survive If Your Parachute Fails To Open: 12 Steps
I loved everything about this place. The people, the experience and I can’t wait to come back for another jump. Can’t recommend enough. Very professional. Thanks for helping me get one off my bucket list. Skydiving is getting safer and safer every year in the United States. The latest data from the United States Parachute Association (USPA) shows that the number of fatalities per 1,000 jumps is at its lowest rate ever, just 0.006 (in 2015). There are half as many fatalities as there were in the 1970s and testify to the great leaps that have been made in skydiving technology and processes.
Skydiving is inherently a sport of risk. You are jumping out of a plane after all. There will always be some risk involved, just as there is with any sport or even everyday activities like driving a car or crossing the road.
What makes skydiving safer is the ongoing commitment of the skydiving community to reduce risk. We do this through the technological advances in our equipment, the training we carry out and the process we put in place to keep ourselves and others safe. Let’s take a look at skydiving safety statistics, how they compare, and why skydiving continues to attract thousands of new jumpers each year.
USPA – United States Parachute Association – is the advisory body for skydiving here in the USA. Skydiving centers are not required to be members of the USPA, but the majority choose to be in favor of the guidelines and regulations it provides.

The USPA keeps track of the number of deaths and injuries among its members, of which there are more than 35,000 (which includes tandem skydivers, professionals and hobbyists) across 230 affiliated skydiving centers.
The first ever record of skydiving deaths in 1961 showed an average of 3.65 fatalities per 1,000 skydives. As the years have passed and progress has been made, this number has reduced to just 0.006 deaths per thousand in 2015.
Injuries are more common than fatalities in skydiving, but still far less common than you might think. The point is that we jump from a plane and fall at speeds of about 120 mph through the air before deploying our parachutes and coming in to land. It is to be expected that now and again things do not go quite according to plan. Often this is through people simply trying something more advanced than their current skills allow. Other times it’s as simple as someone landing on an ankle the wrong way or even tripping while running off speed.
In 2015, there were 1,920 injuries requiring medical treatment out of 3.5 million jumps, or one injury per 1,806 parachute jumps, according to USPA safety records.

Given the safety statistics posted here, hopefully you’ll agree that it’s pretty unfair for skydiving to be perceived as a “risky” sport.
In fact, there are many other activities you can do that are statistically much less safe, including (according to the National Safety Council):
Be careful if you eat while reading this! Your chances of choking on that delicious morsel are 1 in 3,461.
They are a much more environmentally friendly form of transport than the car, but bicycles are not without risks. One in 4,486 people die in a bicycle-related incident.

These little guys are responsible for pollinating our plants and keeping the world looking and smelling good. But 1 in 63,225 people will die from contact with a hornet, wasp or bee.
Man’s best friend is not always so friendly. The chance of being killed by a dog bite or attack is 1 in 112,400.
A lightning strike is extremely rare – so much so that you may have a greater chance of winning the lottery! The chance of being struck by lightning is 1 in 161,856.
At a rate of 0.006 skydiving deaths per 1,000, there is 1 death in every 167,000 jumps. This means that you are more likely to die from a lightning strike, dog bite, wasp sting, bicycle accident, suffocation or a motor vehicle accident.
How Safe Is Tandem Skydiving
Safety will always be a hugely important consideration for skydivers. Although our safety record continues to improve, we refuse to rest on our laurels.
Since the early days of skydiving, there have been some huge advances in technology, equipment, training and processes.
For example, today’s skydiver always jumps with two parachutes – one main and one reserve. This means that there is always a “spare” if the main parachute does not deploy correctly. The malfunctioning parachute is released by the “3 ring release system”, which was developed by Bill Booth in the 1970s.
We use a device called an AAD (automatic activation device). It sits in our parachute canister and monitors our rate of descent and altitude. In the unlikely event we are unable to deploy our own parachute, the AAD will detect our speed and deploy the backup parachute for us.

It’s not just technology that makes us safer; improvements in processes help us keep track of our own equipment. The USPA even promotes an annual “safety day” for all skydivers. This ensures that their knowledge of safety concerns is up to date.
