In February 2023, BMX rider Kriss Kyle executed a groundbreaking stunt titled “Don’t Look Down,” where he performed tricks on a custom-built skatepark suspended over 2,000 feet above the ground by a hot air balloon. This feat was the culmination of nearly three years of meticulous planning and collaboration with Red Bull Advanced Technologies and Cameron Balloons.

Conceptualization and Planning

The idea originated during the COVID-19 lockdown when Kyle envisioned riding a skatepark in the sky. He initially considered suspending the structure beneath a helicopter but realized that the downdraft would create unfavorable riding conditions. This led to the innovative solution of using a hot air balloon, which provides a more stable and wind-free environment.

Engineering the Floating Skatepark

To bring this vision to life, Kyle partnered with Red Bull Advanced Technologies, the engineering division of the Oracle Red Bull Racing Formula One Team. The team designed a lightweight yet robust BMX bowl using carbon fiber composites, similar to those used in Formula One cars. This material choice was crucial in reducing the structure’s weight to approximately 1.7 tons, making it feasible for aerial suspension.

Cameron Balloons, a leading hot air balloon manufacturer, constructed one of the world’s largest operational hot air balloons to lift the skatepark. The balloon’s envelope was six times larger than standard models, providing the necessary lift and stability for the 1.7-ton structure.

Overcoming Challenges

Executing the stunt required overcoming significant challenges, including precise weather conditions. The team needed a rare combination of high atmospheric pressure, cold and dry air, and surface wind speeds below 3 mph to safely launch and operate the massive balloon. After nearly a year of monitoring weather patterns, a suitable window emerged in February 2023.

Kyle also had to adapt to riding with a parachute, which added approximately 20% to his body weight and affected his balance and maneuverability. Additionally, the movement of the bowl, influenced by air currents and the balloon’s motion, introduced an unpredictable element to his performance.

The Stunt Execution

On the day of the stunt, the balloon launched from Charlton Park Estate in Wiltshire, England, and traveled approximately 30 miles over the Cotswolds. Suspended beneath the balloon, Kyle performed a series of complex BMX tricks, including backflips and 360-degree spins, all while contending with the bowl’s movement and the challenges of high-altitude conditions.

Reception and Impression

“Don’t Look Down” received widespread acclaim for its innovative blend of extreme sports and engineering. The project not only showcased Kyle’s exceptional BMX skills but also highlighted the possibilities of combining advanced technology with athletic performance. The stunt was documented in a film that provides an in-depth look at the planning, challenges, and execution of this remarkable feat.

This endeavor stands as a testament to human creativity and the relentless pursuit of pushing the boundaries of what’s possible in both sports and engineering.
