Wingsuit flying

People wear special suits to fly.

These suits have cloth wings. The wings help you glide. You do not just fall. You move forward through the air. You can jump from a plane. You can jump from a cliff. Some people call them bat suits. They look like bat wings. You must use a parachute to land safely. It is a very big thrill!

Wingsuit flying is a sport where people glide through the air.

Instead of just falling, they wear a special suit. This suit has fabric wings between the arms and legs. These wings help the flyer lift up and move forward. Some people call these "birdman suits." Others call them "bat suits" because they look like bat wings.

Flyers can jump from a plane. They can also jump from a cliff or mountain. This is called BASE jumping.

When they jump, air fills the suit. This makes the suit firm like a wing. A skilled pilot can glide three meters forward for every meter they fall.

To fly, pilots move their bodies. They roll their shoulders or move their hips. This helps them steer. They also use tools like GPS to track their path. Every flight must end with a parachute. The pilot throws a small chute to open the big one. This lets them land safely on the ground.

Wingsuit flying is an exciting sport that lets people glide through the sky.

Instead of just falling straight down, flyers wear a special jumpsuit. This suit has fabric membranes between the arms and the sides of the body. Some designs even have fabric between the legs to act like a tail. These wings help the person create lift from the wind. This allows them to fly forward rather than just dropping. People often call these "birdman suits" or "bat suits" because of how they look.

Flying a wingsuit involves several careful steps. First, the pilot must exit an aircraft or a high object like a cliff. If they jump from a plane, they must manage the airflow as they leave. If they jump from a cliff, they use gravity to build up speed. This speed fills the suit with air to make it firm. The suit becomes a shape called an airfoil. To steer, the pilot moves their body in specific ways. They might roll their shoulders or move their hips and knees.

People have tried to fly like birds for a very long time. In 1912, a tailor named Franz Reichelt jumped from the Eiffel Tower. He was testing a suit that combined a wing and a parachute. Much later, in 1930, Rex G. Finney used a wingsuit in the United States. Early suits were made of materials like canvas, silk, and even whalebone. They were not very reliable back then. Modern suits are much better because of new science.

In the late 1990s, the modern wingsuit was truly born. A man from France named Patrick de Gayardon helped develop it. In 1997, Sammy Popov built a suit with a larger wing between the legs. He tested his design in a wind tunnel in Las Vegas. Another builder, Chuck Raggs, added hard ribs to help the wings keep their shape. By 1999, Jari Kuosma helped make wingsuits safer for everyone. He started a company called Birdman to teach new pilots.

Today, wingsuit flying is a highly skilled activity. Pilots use tools like GPS to track their flight paths. They want to see how well they glide through the air. A good pilot can achieve a glide ratio of 3:1. This means they move three meters forward for every meter they fall.

Every flight must end safely with a parachute. The pilot flairs to slow down before throwing a small chute. This starts the process of opening the big parachute for a landing.

Wingsuit flying is a specialized discipline of skydiving that uses a webbing-sleeved jumpsuit to transform a free fall into a period of gliding flight.

This sport relies on a wingsuit, which is a garment featuring fabric membranes stretched between the arms and the flanks or thighs. Many designs also include a membrane between the legs to function as a tail for aerial steering. By increasing the surface area of the human body, the suit generates lift, which is the upward force that opposes gravity. This allows the pilot to achieve extended air time by moving horizontally through the sky rather than simply dropping vertically.

The mechanism of flight begins with a launch from either an aircraft or a fixed object, such as a cliff or mountain top. In skydiving, the pilot exits an airplane and must manage their orientation relative to the aircraft's forward speed and airflow. In BASE jumping, the pilot jumps from a fixed object and relies on gravity to create the necessary airspeed.

As the pilot falls, air enters the suit through specific inlets, inflating the fabric into a semi-rigid airfoil shape. To control this shape, the pilot manipulates their body configuration. They might de-arch their back, roll their shoulders, or move their hips and knees to change the angle of attack. This angle determines how the wingsuit interacts with the relative wind.

Wingsuit designs vary significantly based on their intended use and the pilot's skill level. One common type is the tri-wing design, which features three individual ram-air wings attached under the arms and between the legs. Another approach is the mono-wing design, where the entire suit functions as one large, continuous wing. Beginner wingsuits are designed with less surface area and lower internal pressure to ensure they are easier to control. As pilots gain experience, they often transition to advanced suits with larger surface areas to achieve higher glide performance.

The history of human attempts to fly like birds is filled with both early failures and modern breakthroughs. In 1912, a tailor named Franz Reichelt attempted to test a combination of a wing and a parachute by jumping from the Eiffel Tower. Later, in 1930, Rex G. Finney used an early wingsuit in the United States to increase maneuverability during parachute jumps. These early versions were made of materials like canvas, silk, wood, and even whalebone. The modern era of the sport began in the mid-1990s when Patrick de Gayardon developed a suit adapted from models by John Carta.

Innovation continued through the late 1990s with various specialized designs. In 1997, Sammy Popov built a prototype with a larger leg wing and tested it in a vertical wind tunnel in Las Vegas. In 1998, Chuck Raggs developed a version featuring hard ribs inside the wing airfoils to maintain shape, though the added weight made it harder to fly. By 1999, Jari Kuosma and Pečnik created the "Classic" suit for Birdman International, the first wingsuit offered to the general public. Kuosma also established an instructor program to provide standardized training for skydivers with at least 200 jumps.

Performance in wingsuit flying is often measured by the glide ratio. This ratio compares the horizontal distance traveled to the vertical distance dropped. While older suits from the 1990s often had a ratio of 2:1, modern advancements allow pilots to achieve a ratio of 3:1 or more.

This means for every one meter of descent, the pilot moves three meters forward. Pilots also use a maneuver called a flare, where they dive to build speed and then exchange that airspeed for a brief increase in altitude. To track these metrics, many pilots use portable GPS receivers to analyze their speed, fall rate, and flight paths.

Every wingsuit flight must conclude with a safe deployment of a parachute. Before deployment, the pilot performs a flare to reduce their airspeed. The pilot then reaches back to throw a pilot chute, which initiates the parachute sequence. It is important to note that the pilot must unzip the arm wings after the parachute is out to reach the steering toggles. This ensures the pilot can control their descent path and land at a chosen location. This combination of aerodynamic skill and specialized equipment allows humans to experience a unique form of controlled flight.
