Rescuers have located five of seven people trapped in a flooded cave in Laos, but extracting them remains fraught with challenges. Low oxygen supplies, dark and narrow spaces, and the threat of more rain complicate the operation, according to officials involved in the mission.
The chamber where the five were found is about 300 metres from the cave entrance, but reaching it required crawling for hundreds of metres through flooded areas and tunnels as narrow as 60 centimetres. Finnish diver Mikko Paasi described the environment as “extremely remote and hostile,” with a four-kilometre jungle track leading to the site and constant hazards inside.
Grant Pearce, national director of the Cave Divers Association of Australia, compared navigating the cave to “going to visit somebody’s house that you haven’t been to before, all the lights are off.” Divers run a fixed line from the surface to maintain a tactile reference in zero-visibility conditions, akin to breadcrumbs.
Kengkard Bongkawong, head of operations for Thai rescue group Metta Tham Rescue, appealed for oxygen tanks, stating at least 30 are needed for rescuers and the trapped men. He noted that the extraction “isn’t easy,” as the trapped individuals likely lack dive experience and may panic, making rescue more dangerous.
Unlike the 2018 Thai cave rescue, where schoolboys were sedated and tethered to divers, Pearce emphasised that each rescue is unique. The current operation involves international and Thai divers, including some who assisted in the Thai mission.
