Flying squirrels, because flying squirrels don't really fly when they descend from high altitudes, but they glide, and at this time flying squirrels have limbs, leather wings between the front and back, and when humans descend, they also parachute.
Parachute = leather wing.

The parachute is derived from the animals flying monkeys, quolls, and treetop possables. The world's last remaining gliding animal, the flying monkey has sturdy kite-like wings and can glide up to 400 meters with the help of air currents. Quolls and treetop possums can glide up to 100 metres.
People think of things like flying monkeys, which have a thin, wide membrane-like that glides, escapes, and even flies. People thought of cloth, which was constantly improved and became the style it is today.
The parachute was first invented by the Arabs. More than 1,000 years before the Wright brothers invented airplanes, an Arab made flying machines out of wood and cloaks, and his flying machines are considered the first prototypes of parachutes. In order to ensure the safety of people in the air, parachutes on the acrobatic field began to enter the aviation field.
At that time, someone made a kind of silk hard skeleton parachute, placed on the outside of the balloon basket in a half-open state, with a parachute line under the umbrella jacket, tied to the person's body, if the balloon crashed, that is, the parachute landed.

The parachute was invented in imitation of animals such as flying monkeys, bandling squirrels, and treetop possums, which are among the few gliding animals in the world, such as flying monkeys, which have solid, kite-like wings that allow them to glide for about 400 meters with the help of air currents. Quolls and treetop possums can also glide for about 100 meters. People observed their wings and invented something like a wide membrane with a thin light, which later evolved into a parachute.
Because the parachute uses a light and thin fabric that imitates the wings of flying monkeys and quolls, the parachute can glide, escape, and even fly, and then it has been continuously improved, and different styles have come out to suit various environments and flight modes.
Gliders generally inhabit tree cavities in tropical forests individually or in groups, and are hung on the walls of caves with claw hooks. Usually they start going out at dusk and return to the cave before dawn. When going out, they tend to glide down a fixed route.
Because he has a strong gliding ability, he is good at climbing trees, and often jumps from tree to tree. Generally speaking, gliders are not fast on the ground, and they cannot even stand upright on the ground, but can only move slowly, so they will not easily go to the ground. Gliders generally feed on young leaves, stems, flowers, and certain fruits.
We see on TV or in movies those skydivers jumping out of airplanes and then the parachute opens out of their bag and holds the skydiver in the air. Actually, this requires preparation in advance. Before skydiving, skydivers undergo a period of training, and only those who are in the right physical condition can skydive. >>>More

A person can use a parachute, and a large parachute is needed to pull a person. If it is an airplane, 100 tons of weight * aircraft speed (two or three hundred meters per second) = momentum, do you know how big this momentum is? At least 10 parachutes the size of Tiananmen Square are needed. >>>More
Legend has it that around 1306 AD, during the enthronement ceremony of an emperor of the Yuan Dynasty, such a program was performed in the court: acrobats leaped down from a high wall with a giant paper umbrella. Due to the use of the principle of air resistance, the artist landed safely and soundly, which can be said to be the earliest practice of skydiving. >>>More
