About the Sport

A few seconds of freefall. Years of preparation.

BASE jumping is a sport defined by commitment, precision and consequence. To understand the stories featured in this documentary, it helps to first understand the culture, history and realities of the sport itself.

BASE

What is BASE Jumping?

BASE jumping involves parachuting from fixed objects rather than aircraft. Unlike skydiving, where jumps begin at high altitude, BASE jumps often take place much closer to terrain, structures and obstacles.

The reduced time available after exit leaves little margin for error and requires extensive preparation, specialised equipment and sound judgement.

While many participants are drawn to the sport by adventure, challenge and exploration, BASE jumping remains one of the highest risk recreational activities in the world.

What BASE stands for

  1. 01

    B

    Building

    Urban structures and towers where access, wind and landing areas create complex constraints.

  2. 02

    A

    Antenna

    Masts and antenna structures, often exposed to weather and access limitations.

  3. 03

    S

    Span

    Bridges and similar spans where object height, airflow and landing options vary widely.

  4. 04

    E

    Earth

    Cliffs, mountains and natural formations that define much of the alpine BASE environment.

Historical timeline

History of BASE Jumping

  1. 1783

    Early parachute experiments

    Parachute ideas appear long before the modern sport. For centuries, people experimented with jumps from towers, cliffs and balloons before BASE jumping became a defined practice.

  2. 1970s

    Carl Boenish

    A skydiver, filmmaker and pioneer helps turn isolated fixed-object jumps into a recognisable activity. His films and organising work shaped how the early scene understood itself.

  3. 1978

    El Capitan

    A series of Yosemite jumps with modern ram-air parachutes becomes a defining origin point. These El Capitan jumps are often described as the beginning of modern BASE jumping.

  4. 1981

    BASE Number System

    The four object categories become part of the sport's identity. Jumpers who completed Building, Antenna, Span and Earth could apply for an official BASE number, a tradition that continues today.

  5. 1990s

    Small community growth

    Knowledge circulates through mentorship, personal networks and direct experience. Limited access to equipment and experienced jumpers creates a culture built around patience, commitment and learning from others.

  6. 2000s

    Internet and forums

    Information and imagery begin circulating globally. Online forums, digital cameras and video platforms make knowledge easier to access, while also spreading dramatic images beyond the community.

  7. 2010s

    Social media visibility

    Video platforms shape how the public sees the sport. Spectacular footage brings BASE jumping to new audiences, but often shows the jump itself more clearly than the preparation behind it.

  8. 2020s

    Modern BASE scene

    Global travel, technology and media connect athletes worldwide. Even as equipment and communication evolve, gravity, weather, terrain and human decision making remain the defining factors.

Basejumping vs. Skydiving

Very limited time

  1. 01

    Skydiving altitude

    You leave an aircraft at around 3,000-4,000 metres. That altitude creates a long vertical window for body position, awareness and parachute deployment. A skydiver usually opens their parachute at around 1,000 metres.

  2. 02

    More available margin

    There is more altitude, more time and usually a main canopy plus a reserve. Skydiving rigs also commonly include an AAD, an automatic activation device, which can initiate reserve deployment in specific emergency conditions.

    • More time to react
    • Main + reserve canopy
    • AAD backup system

  3. 03

    BASE altitude

    In BASE jumping, the exit point can be only a few hundred metres above the ground. Terrain, objects and landing areas are close from the moment of exit.

  4. 04

    Decision pressure

    That means very limited reaction time. Choices about weather, equipment, exit technique and landing plan must be made before the jump begins.

    A mistake has less space to unfold safely.

  5. 05

    Everything changes

    This changes everything: equipment, decisions, landing options and safety culture. The table below summarises the practical differences behind that pressure.

  1. 01

    Canopy

    Most BASE systems use a single canopy designed for low-altitude openings. These parachutes are generally larger, more stable and built to open quickly and predictably.

  2. 02

    Container

    The container holds the canopy and is built to stay lightweight and streamlined while remaining durable enough for demanding fixed-object environments.

  3. 03

    Pilot chute

    A small auxiliary parachute that extracts the main canopy from the container. Depending on the jump, it may be handheld, stowed or assisted.

  4. 04

    Helmet

    Helmets are standard throughout the sport and form part of the protective setup used around terrain, structures and restricted landing areas.

  5. 05

    Optional: Tracking suit or wingsuit

    Used on longer freefall jumps to improve aerodynamic performance and horizontal movement before deployment, while adding complexity and risk.

  6. 06

    Optional: Body protection

    Back protectors, knee pads, ankle support or impact-resistant clothing may be used depending on terrain, discipline and landing conditions.

Disciplines of BASE Jumping

01

Traditional BASE / Slick

The foundation of the sport: exit a fixed object, maintain stability during freefall and deploy the parachute safely before landing. These jumps place strong emphasis on preparation, canopy control and decision making rather than aerial performance.

02

Tracking

A form of human flight that uses body position or specialised tracking suits to increase horizontal movement during freefall. Athletes aim to move away from the object while managing aerodynamics, body control and terrain awareness.

03

Wingsuit BASE

Combines a wingsuit with a BASE parachute system. The wingsuit creates lift and allows long glides before deployment, making it one of the most visible and technically demanding disciplines in the sport.

04

Aerials and Acrobatics

Some athletes perform flips, spins or other acrobatic movements before deployment. These jumps require precise timing, body awareness and altitude management.

05

Urban BASE

Jumps from buildings or other urban structures, where access, wind effects, obstacles and landing areas create complex constraints beyond the jump itself.

06

Low Object Jumping

Not all jumps involve extended freefall. Very low objects require specialised deployment techniques designed for immediate parachute inflation, with careful preparation and precise equipment configuration.

07

Multi Way Jumps

Two or more athletes exit together and coordinate movement, formations or shared flight paths. Communication, planning and trust are critical.

08

Ski BASE

A skier exits from a cliff or mountain face and deploys a parachute after leaving the snow. It combines alpine skiing, terrain judgement and BASE-specific deployment skills.

09

Tandem BASE

A highly specialised format where two people jump with one parachute system. It is rare, tightly controlled and depends on expert-level equipment setup and decision making.

  4. 04Judgement

Equipment is important. Decision making is critical.

A shared responsibility

Community and Ethics

BASE jumping extends beyond the individual athlete. Every decision sits inside a wider ecosystem.

  1. 01

    Mentors

    Pass on site knowledge, progression standards and lessons that help newer jumpers make better decisions.

  2. 02

    Athletes

    Carry responsibility for preparation, judgement and the way their choices affect access and others.

  3. 03

    Community

    Creates informal norms around learning, restraint, respect and accountability.

  4. 04

    Landowners

    Shape access through trust, local relationships and expectations around respectful behaviour.

  5. 05

    Public

    Sees the sport through shared images, reports and stories, making representation part of the ethics.
