France, Ardèche region, Dragonniere  Eric Establie

Eric Establie, an experienced diver, finds himself trapped deep within the pitch-black Dragonniere Cave. His only chance of survival lies in finding an airspace on the other side of a rockfall. However, the rockfall has sealed him within the cave. This dire situation prompts a rescue mission. Only eight divers in the world are considered capable of carrying out such a complex rescue.

One rescue diver acknowledges that embarking on such a mission is fraught with uncertainty. The possibility of a tragic outcome is ever-present, leading rescuers to brace themselves for the worst. Eric’s journey through the unexplored parts of Dragonniere Cave is a graphic account of his ordeal. Despite the extensive exploration of the cave by Eric and his friends, it remains relatively unknown and infrequently visited. Situated in the Ardèche region of France, this area boasts beauty but hides deadly water-filled caves beneath its surface.

Diving into the Technical Challenge

Dragonniere Cave poses significant technical challenges due to its intricate passages and potential for entrapment. Eric is drawn to such challenges, despite the high risk of becoming trapped in uncharted portions of the cave, increasing the likelihood of panic and reducing the chances of escape. The cave’s silty nature also dissuades divers; limited visibility, often just a few feet, adds to the danger. Operating in such conditions demands extreme caution to prevent silt disturbances that could lead to blindness and disorientation.

Air pockets within the cave may seem tempting for a respite, but caution is advised, especially for less experienced divers. These pockets might contain bad air, leading to physical impairment, acidosis, and potentially fatal consequences. Eric meticulously considers these risks and dedicates extensive time to preparation. His unwavering passion for cave diving, particularly the exploration of unseen areas, drives him.

Eric’s Passion and Personality

Eric Establie, a 46-year-old diver, balances his underwater engineering business, family, friends, and diving fervor. He began his cave diving journey in the 1990s, ultimately mastering the art of challenging cave dives that few would dare attempt. His dedication to mapping uncharted cave sections, notably Dragonniere Cave, is evident. Eric’s enthusiasm and warm personality endear him to others in the diving community. His smile and positive presence light up any room he enters.

Eric’s family, particularly his wife Evelyn and son Arthur, support his passion. Evelyn encourages him to pursue his dreams, while Arthur follows in his father’s footsteps after initially being introduced to the sport on a school trip. Eric’s numerous diving companions, including Didu, Felipe, and Emrick, join him on various expeditions, sharing stories and experiences. Eric’s legacy extends to his contribution to cave rescues, reflecting his cool-headedness even in the face of extreme challenges.

Trapped in Darkness

On October 3rd, 2010, Eric enters Dragonniere Cave with the goal of exploring its unmapped sections. Carrying an array of equipment, he embarks on a dive that is meant to last six hours. However, challenges emerge. Silt blackouts occur, reducing visibility, and making navigation treacherous. Eric faces silt disturbances and unexpected obstacles as he journeys deeper into the cave.

Finally, Eric finds himself on the wrong side of a rockfall, surrounded by darkness. He must find a way to escape the cave or face the grim reality of being trapped with dwindling air supply. With limited options, Eric makes the difficult decision to leave some of his equipment behind, hoping rescue teams will recognize his intention to survive.

A Race Against Time

News of Eric’s absence triggers a rescue effort led by British and Swiss divers, including Rick Stanton and John Volanthen. These experienced divers, known for their roles in high-profile rescues, arrive at the cave’s entrance. Rick and John’s reputation as accomplished divers precedes them, making them the prime candidates for this complex rescue mission.

Despite the silt-filled, perilous conditions, the two divers enter the cave with first aid supplies and provisions. Their plan involves navigating through the water to reach Eric and initiate his rescue. As they make their way through the cave’s treacherous passages, the race against time intensifies.

The Rescue Mission Unfolds

Searching the Depths

The initial rescue attempt involves British divers Rick Stanton and John Volanthen. After diving 2,427 feet into the cave, they discover the reason for the thick sediment: an underwater avalanche has stirred up the mud on the cave floor. Despite their efforts, their bulky equipment prevents them from traversing a small hole in the rockfall, situated 2,559 feet from the entrance. Low air supply forces them to retreat without finding Eric.

Adapting the Plan

Armed with newfound insight, the divers devise a new rescue plan and gather supplies for another attempt. Meanwhile, civil engineers work to excavate an impassable vertical shaft, aiming to access an upstream section of the cave. Simultaneously, a team explores a nearby cave that could potentially connect to Dragonniere Cave, offering an escape route for Eric.

The Swiss Diving Team’s Attempt

The Swiss diving team launches another rescue operation as visibility within the cave improves. They reach the rockfall without difficulty but struggle to find a passage through. They retreat to resupply. A backhoe clears a trench, granting access to a Fisher where cavers work to connect with Dragonniere Cave. A narrow aperture holds potential to lead to an air-filled passage where Eric might be waiting.

A Risky Maneuver

Rick and John make their second rescue attempt, collaborating with expert divers Pedro Barlowdy and Luigi Castelli. They utilize a slimmer diving apparatus to navigate through a narrow gap within the rockfall. Upon revisiting the spot of Eric’s emergency scooter, they discover he attempted to crawl through the obstruction, revealing a passable gap. Despite the risk, they plan for a third rescue dive.

A Glimmer of Hope

After resupplying, Rick and John reenter the cave, quickly reaching the obstruction. They push through the gap near the rockfall’s top, navigating cautiously to avoid silt blackouts. Progressing deeper into the unexplored cave, they hold onto the hope of finding Eric alive.

The Tragic Discovery

Their determination leads them to Eric, 15 feet below them. The depth at which they find him astonishes them. It becomes clear he was seeking an airspace but ran out of air before reaching safety. Eric’s body is eventually located, concluding a 10-day search. Efforts to recover his body are complicated by the cave’s narrow passages.

The Unfortunate End

The recovery process proves arduous, with Eric’s body getting stuck in a gap within the rockfall. Despite their best efforts, Rick and John are forced to leave the body behind due to safety concerns. Their priority shifts to retrieving Eric’s diving computer, which holds crucial information about his dive progression and final moments.

The Ongoing Effort

As they exit the cave, the divers face their own challenges in making it out safely. Low air levels and the distance covered make their exit a close call. They successfully return to the cave entrance, handing Eric’s diving computer to authorities. The computer sheds light on Eric’s journey and ultimate fate.

The Search’s Conclusion

Unyielding Persistence

Despite weeks of effort, Eric’s body remains in the cave. French speleologists continue their attempts to access and recover his remains, employing drilling techniques to break through rock. The search officially ended on January 8, 2011, yet the effort to retrieve Eric’s body persists.
