Swiss Authorities Drop Criminal Investigation into Death of Scottish Wingsuit Flyer Liam Byrne

Swiss prosecutors have decided to close their investigation into whether any crime was committed in connection with the death of a Scottish wingsuit flyer who suffered fatal injuries during a jump in the Swiss Alps last year. The decision brings an end to legal proceedings that had been examining the circumstances surrounding the death of 24-year-old Liam Byrne, a British champion in the extreme sport.

Byrne, who was from Stonehaven in Aberdeenshire, was fatally injured on the Gitschen mountain after taking off from an altitude of approximately 7,874 feet (2,400 metres) in June last year. Documents from the Swiss Federal Prosecutor's Office, which were reviewed by BBC Scotland News, confirm that authorities made the decision to discontinue proceedings following their assessment of the evidence.

The young flyer had been featured in a 2024 BBC documentary titled "The Boy Who Can Fly," which chronicled his remarkable journey in extreme sports. Described as a highly experienced wingsuit flyer, Byrne had completed thousands of jumps throughout his career. Wingsuit flying is a specialised form of skydiving in which participants wear a suit equipped with webbing between the arms and legs, designed to create lift and allow controlled movement through the air.

According to the Swiss Federal Prosecutor's Office report explaining the decision to discontinue the investigation, the first two wingsuit jumpers in Byrne's party had landed without any issues. However, the report stated that Byrne collided with the mountainside, sustaining injuries that proved fatal. The document noted that proceedings would be discontinued in cases where there is insufficient evidence of criminal suspicion, including situations involving knowingly placing life in danger.

The report offered a detailed technical assessment of the incident, concluding that the fatal crash was, with a high degree of probability, attributable to a situation from which there was no escape. This situation resulted from insufficient lift combined with the low altitude above the ground at the time of the jump. The findings suggest that Byrne found himself in an irrecoverable position during the flight.

Crucially, the investigation found no indications of any criminal acts by third parties that might have contributed to the crash. Furthermore, authorities identified no evidence of a pre-existing technical defect in the equipment Byrne was using that could have played a role in the incident. These conclusions formed the basis for the decision to formally discontinue the proceedings.

Byrne's journey in extreme sports began at a remarkably young age. He told the BBC documentary that he first expressed his ambition to fly like a bird to his father when he was approximately 13 years old. His adventurous spirit manifested early, and at just 12 years old, he climbed Mount Kilimanjaro, Africa's highest peak, which stands at 19,341 feet (5,895 metres).

That early mountaineering achievement led Byrne to pursue a wide range of outdoor adventures, including dog-sledding through the Arctic, scuba diving, and numerous high summit climbs. By the age of 14, he had already obtained his licence as a paraglider, demonstrating a precocious talent for aerial sports. He completed his first skydive at 16 and, by 18, had begun flying in a wingsuit, which he described as a "second skin" that allowed him to move through the air in a controlled manner.

Following his death, Byrne's family issued a statement paying tribute to his life and character. They expressed a desire for him to be remembered not merely for the circumstances of his passing but for the way he had lived. The family described him as fearless, explaining that this quality stemmed not from an absence of fear but from his refusal to allow fear to hold him back.

The family's tribute emphasised that Byrne pursued life with an intensity that most people only dream about. They noted that skydiving and base jumping represented far more than simple thrill-seeking for him, describing these activities as a form of freedom and the environment in which he felt most alive. This sentiment underscored the deep personal significance that extreme sports held for the young flyer.

The decision to discontinue the investigation means that Swiss authorities have concluded there is no basis for pursuing criminal charges in connection with the incident. The findings of the Swiss Federal Prosecutor's Office point to a tragic accident rather than any wrongdoing, with the technical assessment indicating that Byrne encountered an unavoidable situation during his final jump.

The case has drawn attention to the inherent risks associated with wingsuit flying, an extreme sport that demands extensive experience and carries significant danger. Despite the precautions taken by experienced practitioners such as Byrne, the sport's very nature involves operating in a high-risk environment where variables such as altitude, lift, and terrain can have critical consequences.

Byrne's death at the age of 24 cut short a life that had already encompassed an extraordinary range of achievements and experiences. His story, documented in the BBC film that introduced him to a wider audience, serves as a testament to his passion for flight and his determination to push the boundaries of what is possible in the air. The discontinuation of the legal investigation brings a formal conclusion to the examination of the circumstances surrounding his final jump.
