Skydiving: truth and fiction
Parachuting is one of the most extreme sports that a man could think of. Very few people decide to jump with a parachute – and very few people, having decided to jump to nowhere, continue this dangerous occupation. As in any sport, there are laymen who consider themselves to be true professionals. It is thanks to such people that unconfirmed facts and rumors often turn out to be among the uninitiated, which turn out to be lies and fiction. In this post we will try to talk about the most common myths of parachuting.
Two prashutists can calmly talk, being close to each other in a state of free fall.
In some very truthful films, parachutists do talk in the air, but this is nothing but a legend. No matter how you scream, a person falling near will not hear anything. That is, not just nothing, but absolutely nothing: you fall so fast that the sound just does not have time to reach the interlocutor, shaking the air somewhere above.
Maybe if you scream in your ear, something will be heard, but not a fact. By the way, about the beloved fights of many directors in the air – maybe a professional skydiver can hit someone falling nearby. But even for a professional it will be very difficult to carry out all the tricks that we see in action movies.
When the parachute opens, the skydiver rises slightly upward.
All this is only an optical illusion, seen by us on TV – for who shoots parachutists? Either the same skydivers falling alongside, or a person on any aircraft flying down at a certain speed. Naturally, as soon as the parachute opens, the speed at which the parachutist falls is immediately slowed down, and for an outside observer the parachutist “jumps”, remaining at the top.
The skydiver always packs his parachute himself
Yes, many parachutists do prefer to fold their own parachute on their own, but in general, usually a parachute is formed by specially trained people who know how to do it very well. Naturally, such services are not free – “packers” charge for their services from 5 to 7 dollars for one installation.
But of course, it is best to learn how to do it yourself, without relying on the attentiveness and good faith of outsiders. By the way, there are various options for laying parachutes, which allow you to soften the blow when the parachute is opened.
You can open a parachute at any height
Films about special forces again mislead us – we see the soldier open the parachute just above the ground, remaining unnoticed when landing. The facts are that the parachute must be opened at a height of not less than 180-300 meters above the ground. Of course, you can fold your parachute so that it will jump out almost instantly. But we must not forget about the dynamic impact that occurs when a parachute is opened. A normally laid parachute opens gently, without harming the parachutist. If, however, the parachute is folded for instant operation, then at a sufficiently high fall rate, the opening of the parachute can simply kill or maim the parachutist.
Many novice skydivers think that athletes, jumping from a great height, need oxygen masks, because there you can simply suffocate. The reality is that the oxygen mask is needed only on the plane, and when jumping it is removed – all because at high altitude, where the air is very thin, the parachutist will be very short, falling down at high speed.
