Wingsuiting – Adrenaline Amplified

Wingsuiting is a relatively new discipline that falls under parachuting umbrella, or should I say canopy, the modern wingsuit, first developed in the late 1990's, creates a surface area with fabric between the legs and under the arms. Wingsuits are sometimes referred to as "birdman suits" (after the makers of the first commercial wingsuit), "squirrel suits" (from their resemblance to flying squirrels' wing membrane), and "bat suits" (due to their resemblance to the animal or perhaps the superhero).

A wingsuit flight normally ends by deploying a parachute, and so a wingsuit can be flown from any point that provides sufficient altitude for flight and parachute deployment — normally a skydiving drop aircraft or Base-jump exit point such as a high cliff or a safe mountain top. The wingsuit flier wears parachute equipment specially designed for skydiving or BASE jumping. While the parachute flight is normal, the canopy pilot typically unzips arm wings (after deployment) to be able to reach the steering parachute toggles and control the descent path.

An early attempt at wingsuit flying was made on 4 February 1905 by a 33 year-old tailor, Frank Reichelt, who jumped from the Eiffel Tower to test his invention of a combination of parachute and wing, which was similar to modern wingsuits. He misled the guards by saying that the experiment was going to be conducted with a dummy. His jump unfortunately ended in disaster when he hit the ground headfirst and was killed instantly.

A wingsuit was first used in the US in 1930 by a 19 year-old American, Rex G Finney of Los Angeles, California, as an attempt to increase horizontal movement and manoeuvrability during a parachute jump. These early wingsuits were made of materials such as canvas, wood, silk, steel, and whalebone. They were not very reliable, although some "birdmen", notably Clem Sohn and Leo Valentin, claimed to have glided for miles.

In the mid-1990s, the modern wingsuit was developed by Patrick de Gayardon of France, adapted from the model used by John Carta. In 1997, the Bulgarian Sammy Popov designed and built a wingsuit which had a larger wing between the legs and longer wings on the arms. His prototype was developed at Boulder City, Nevada. Testing was conducted in a vertical wind tunnel in Las Vegas at Flyaway Las Vegas. Popov's wingsuit first flew in October 1998 over Jean, Nevada, but it never went into commercial production.

In 1998, Chuck "Da Kine" Raggs built a version which incorporated hard ribs inside the wing aerofoils. Although these more rigid wings were better able to keep their shape in flight, this made the wingsuit heavier and more difficult to fly. Raggs' design also never went into commercial production. Flying together for the first time, Popov and Raggs showcased their designs side-by-side at the World Free-fall Convention at Quincy, Illinois, in August 1999. Both designs performed well. At the same event, multiple-formation wingsuit skydives were made which included de Gayardon's, Popov's, and Raggs' suits.

In 1999, Jari Kuosma of Finland and Robert Pečnik of Croatia teamed up to create a wingsuit that was safe and accessible to all skydivers. Kuosma established Bird-Man International Ltd. the same year. BirdMan's "Classic", designed by Pečnik, was the first wingsuit offered to the general skydiving public.

BirdMan's "Classic"

BirdMan was the first manufacturer to advocate the safe use of wingsuits by creating an instructor program. Created by Kuosma, the instructor program's aim was to remove the stigma that wingsuits were dangerous and to provide wingsuit beginners, generally, skydivers with a minimum of 200 jumps, with a way to safely enjoy what was once considered the most dangerous feat in the skydiving world. With the help of Birdman instructors Scott Campos, Chuck Blue, and Kim Griffin, a standardized program of instruction was developed that prepared instructors. Wingsuit manufacturers Squirrel Wingsuits, TonySuits Wingsuits, Phoenix-Fly, Fly Your Body, and Nitro Rigging have also instituted coach training programs.

The wingsuit flier enters free fall wearing both a wingsuit and parachute equipment. Exiting an aircraft in a wingsuit requires skilled techniques that differ depending on the location and size of the aircraft door. These techniques include the orientation relative to the aircraft and the airflow while exiting, and the way in which fliers spread their legs and arms at the proper time so as not to hit the aircraft or become unstable. The wingsuit immediately starts to fly upon exiting the aircraft in the relative wind generated by the forward speed of the aircraft.

Exiting an aircraft

Exiting from a BASE jumping site, such as a cliff, or exiting from a helicopter, a paraglider, or a hot air balloon, is fundamentally different from exiting a moving aircraft, as the initial airspeed upon exit is absent. In these situations, a vertical drop using the forces of gravity to accelerate is required to generate the airspeed that wingsuits need to generate lift. At a planned altitude above the ground in which a skydiver or BASE jumper typically deploys the parachute, wingsuit fliers will also deploy their parachutes. The parachute is flown to a controlled landing at the desired landing spot using typical skydiving or BASE jumping techniques.

BASE jumping

A wingsuit modifies the body area exposed to wind to increase the desired amount of lift with respect to drag generated by the body. With training, wingsuit pilots can achieve sustained glide ratio of 2.5:1 or more. This means that for every meter dropped, two and a half meters are gained moving forward. With body shape manipulation and by choosing the design characteristics of the wingsuit, fliers can alter both their forward speed and fall rate. The pilot manipulates these flight characteristics by changing the shape of the torso, de-arching and rolling the shoulders and moving hips and knees, and by changing the angle of attack in which the wingsuit flies in the relative wind, and by the amount of tension applied to the fabric wings of the suit. The absence of a vertical stabilizing surface results in little damping around the yaw axis, so poor flying technique can result in a spin that requires active effort on the part of the skydiver to stop.

A typical skydiver's terminal velocity in belly to earth orientation ranges from 180–225 km/h. A wingsuit can reduce these speeds dramatically. A vertical instantaneous velocity of 40 km/h has been recorded. However, the speed at which the body advances forward through the air is still much higher. British wingsuit pilot Fraser Corsan set world record for the fastest speed reached in a wingsuit of 396.86 km/h

Wingsuit pilots often use tools including portable GPS receivers to record their flight path. This data can be analysed later to evaluate flight performance in terms of fall rate, speed, and glide ratio. When jumping for the first time at a new location, BASE jumpers will often evaluate terrain using maps and laser range finders. By comparing a known terrain profile with previously recorded flight data, jumpers can objectively evaluate whether a particular jump is possible. BASE jumpers also use landmarks, along with recorded video of their flight, to determine their performance relative to previous flights and the flights of other BASE jumpers at the same site.

Modern wingsuits use a combination of materials in order to create an aerofoil shape. The main surface is typically made from ripstop nylon, with various materials used to reinforce the leading edge, and reduce drag. The tri-wing wingsuit has three individual ram-air wings attached under the arms and between the legs. The mono-wing wingsuit design incorporates the whole suit into one large wing.

As compared to skydiving from an airplane, BASE jumping involves jumping from a "fixed object" such as a cliff. BASE jumping in its modern form has existed since at least 1978, but it was not until 1997 that Patrick de Gayardon made some of the first ever wingsuit BASE jumps combining the two disciplines. Compared to normal BASE jumping, wingsuit BASE jumping allows pilots to fly far away from the cliffs they jumped from, and drastically increase their freefall time before deploying a parachute. Since 2003, many BASE jumpers have started using wingsuits, giving birth to wingsuit BASE.

As suit technology and pilot skill have improved, wingsuit BASE jumpers have learned to control their flight so well that they can fly just meters away from terrain. The practice of flying a wingsuit close to the faces and ridges of mountains is called proximity flying. By flying near terrain, wingsuit pilots feel a greater sense of speed due to having a close visual reference. Loic Jean-Albert of France is one of the first proximity flyers, and his pioneering flying brought many BASE jumpers into the sport. In November 2012, Alexander Polli became the first wingsuit BASE jumper to successfully strike a wingsuit target.

Another variation on which studies are being focused is the wingpack, which consists of a strap-on rigid wing made of carbon fibre. It is a mix between a hang-glider and a wingsuit. The wingpack can reach a glide ratio of 6 and permits transportation of oxygen bottles and other material. On 31 July 2003 the Austrian Felix Baumgartner, jumping from 9 kilometres (30,000 ft), successfully crossed the English Channel in 14 minutes using a wingpack, having covered over 35 kilometres.

On 25 October 2009, in Lahti, Finland, Visa Parviainen jumped from a hot air balloon in a wingsuit with two small turbojet engines attached to his feet. The engines provided approximately 16 kgf of thrust each and ran on JET A-1 fuel. Parviainen achieved approximately 30 seconds of horizontal flight with no noticeable loss of altitude. Parviainen continued jumping from hot air balloons and helicopters, including one for the Stunt Junkies program on Discovery Channel.

Christian Stadler from Germany invented the "VegaV3 wingsuit system" that uses an electronic adjustable hydrogen peroxide rocket. The rocket provides 100 kgf of thrust and produces no flames or poisonous fumes. His first successful powered wingsuit jump was in 2007, when he reached horizontal speeds of over 255 km/h (160 mph).

Fédération Aéronautique Internationale (FAI), the world governing air sports body, established judging criteria for official world record wingsuit formations in February 2015. Prior to this, the largest wingsuit formation recognized as meeting the criteria for a national record consisted of 68 wingsuit pilots, which set a U.S. national record at Lake Elsinore, California, on 12 November 2009. The largest global record was a diamond formation involving 100 wingsuit pilots at Perris, California, on 22 September 2012. These records have since been retired as they do not meet the current rules.

Two World Records have been set since the rules update. A 42 person formation over Moorsele, Belgium, set a FAI record on 18 June 2015. This was broken on 17 October 2015, when 61 wingsuit pilots set the current FAI world record over Perris Valley Airport near Perris, California.

On 23 May 2006, the Australian couple Heather Swan and Glenn Singleman jumped from 21,667 ft off Meru Peak in India, setting a world record for highest wingsuit BASE jump. This record was broken on 5 May 2013, by the Russian Valery Rozov, who jumped from 23,690 ft on Mount Everest's North Col.

On 20 and 21 April 2012, Colombian skydiver Jhonathan Florez set Guinness World Records in wingsuit flying. The jumps took place in La Guajira in Colombia for the following records:

Longest time: The longest (duration) wingsuit flight was 9 minutes, 6 seconds

Highest: The highest altitude wingsuit jump was 37,265 ft

On 23 May 2012, British stuntman Gary Connery safely landed a wingsuit without deploying his parachute, landing on a crushable "runway" built with thousands of cardboard boxes.

Wingsuit flying is dangerous, and the pursuit of it has contributed to a number of notable fatalities since its inception. Despite training and regulation, wingsuit BASE jumping remains a precarious pastime. A 2012 University of Colorado study found that for wingsuit BASE jumping there was approximately one severe injury for every 500 jumps undertaken.
