Helicopter and Drone Searches Continue for Nine Missing South Korean Workers in Nepal
As of September 1, a South Korean joint response team reported no confirmed trace of nine South Korean workers missing after flash floods struck Nepal’s Rasuwa District on August 26. The missing personnel include six employees of Doosan Enerbility and three from Korea South-East Power who were working on the Upper Trishuli-1 hydropower project when contact was lost.
Helicopters have been used to survey the affected mountain area after road damage and difficult terrain constrained access. KBS World reported that Doosan Enerbility conducted a chartered-helicopter search on the morning of August 31, followed by a government-team helicopter search that afternoon. The team also operated a drone from Dhunche with the Nepali military, but reported no meaningful signs.
Earlier South Korean reporting said helicopter operations had been limited by local flight approvals and weather-related safety considerations. Yonhap reported that a government-chartered aircraft conducted visual searches toward the flood area on August 29 but could not land. Independent reporting subsequently corroborated helicopter activity on August 31, while wider rescue operations continued around damaged hydropower infrastructure in Rasuwa.
Why it matters
The operation illustrates the operational value and limits of rotary-wing search in a Himalayan disaster zone. Helicopters can rapidly move teams and search crews over washed-out roads and unstable terrain, but landing access, flight authorization, weather, terrain, and the quality of available search clues can sharply limit their effectiveness. No aircraft type or operator was identified in the available reporting.
