Using an Unmanned Aircraft System (Drone) to Conduct a Complex High Altitude Search and Rescue Operation: A Case Study.

Unmanned aircraft systems, also known as unmanned aerial vehicles or drones, are becoming increasingly common consumer products; their potential applications to search and rescue operations are becoming ever more apparent. A consumer drone was used to locate a mountaineer after he and his climbing partner were separated while summiting Broad Peak in the Karakoram Mountains of northeastern Pakistan, the world's 12th highest summit. The use of a commercial drone in the search for the missing climber allowed for a quick rescue mission, eliminating the need for a fully mobilized rescue party while significantly reducing the risk to the climbers charged with rescuing him. Without the drone, the rescue party would have faced immense challenges, including a vast search area and altitudes near the limits of human physiologic function. With real-time imagery and global positioning system capabilities, drones may become an invaluable tool in search and rescue operations, helping to reduce response time and maintain the safety of responders at high altitude and in many other types of difficult terrain.
