How do 57 people achieve a group skydive? If the parachute does not open during the skydive, will it definitely die? At present, the number of skydivers in the mainland every year has reached 30,000-40,000, and an average of about 100 people experience this exciting sport every day, perhaps you will also become one of the experiencers in the future, and learning these tricks may be able to save a life.
In 2015, in Texas, 57 skydivers decided to hold a group skydive in memory of his friend Bigley, who unfortunately died. One by one, the team members jumped from the plane like dumplings, fell head-to-head, and then slowly gathered together in the air hand in hand, forming a pattern like three hearts strung together, descending at a speed of more than 200 kilometers per hour.
Seeing this, some people must wonder, why do they jump down at different times, and they can still be at the same level in the air? This is because they are in the air, can adjust the posture of their body to control the resistance of the descent, such as contracting the body resistance will become smaller and faster to fall, open hands and feet body parallel to the ground, the descent speed will be slower, by constantly adjusting the descent speed, you can achieve hand-in-hand between teammates. Of course, this requires super high skydiving skills, and a lot of training, before reaching the minimum safe altitude of 500 meters, open the parachute to achieve a safe landing, in case the parachute can not be opened, do not worry too much, there is another spare parachute in the parachute bag, so what if both parachutes fail at the same time?
What if your parachute doesn't open when you skydive? First of all, don't panic, and don't close your eyes to prepare for the table.
In July 2016, American skydiver Luke Akins jumped from a plane wearing only a green jumpsuit, probably afraid of running out, and wearing an oxygen mask. When he descended to about half the altitude, Luke also took the time to remove the oxygen mask and handed it to the jumper carrying the parachute bag, and then the three people opened the parachute, Luke was still spinning in the air and jumping with his eyes closed. Finally, he fell into a large net and broke the Guinness World Record for parachuting without skydiving.
It can be seen that when the parachute cannot be opened, you can get a ray of life by changing the descending posture, the spread of the limbs can slow down the speed of the descent, and adjust the landing position by rotating the back and abdomen, adjusting the position of the arms and other actions. However, in the world record set by Luke, the 30*30 safety net on the ground was customized by a professional team after many tests and rigorous calculations. And you can only use local materials, choose a relatively soft place that can provide you with a cushion to land, such as a place with snow, a wooded forest, try to keep your feet on the ground and protect your head.
In 1972, Yugoslav Flight 367, after the explosion in the air disintegrated, a flight attendant fell just covered with thick snow, survived and was treated by surrounding villagers. In the 1971 Peruvian air disaster, there was also a 17-year-old girl named Julian, who fell from a height of 3,000 meters into the primeval forest and retrieved a small life, but there is a place that cannot be jumped.
Why can't I open a skydive and jump into the water? It turns out that you have been deceived by the TV series for so many years.
In film and television dramas, the main characters who jump off a cliff and fall into the water will inevitably die. But if you do this in reality, you may not be able to complete it. Because people fall into the water from a height, the maximum speed can reach more than 200 km / h, are almost catching up with the high-speed rail, falling on the water will cause a huge impact. And the effect of force is mutual, if your body enters the water horizontally, it is difficult for the water to diffuse to provide you with enough cushioning, hitting it is no different from hitting a cement wall, and the internal organs can smash you. Even professional divers who are able to keep their bodies vertically into the water, shrink the contact area with water, and have a certain cushioning effect, will feel very painful.
At present, the highest diving record set by humans is only 58.8 meters, created by Lazaro Schaller of Switzerland. As an ordinary person, don't try it easily, and without warm-up exercise, even if you are not a dry duck, you may be at risk of cramping and drowning.
Of course, at present, in addition to professional skydivers in China, most people will choose professional skydiving instructors, conduct tandem skydiving together, and also take a VLOG by the way, don't worry about anything, why say so? Under normal circumstances, the coach with the skydiving, there will be no parachute can not be opened, even if the main umbrella can not open there is a secondary umbrella, the secondary umbrella can not be opened or the coach loses consciousness, the monitoring device of the umbrella bag will automatically open the parachute when it reaches a certain height, and the probability of an accident is minimal. In other words, have you ever experienced skydiving in front of the screen?
