.During the 2023 floods, a village was surrounded by floodwaters, forming an ‘island,’ and traditional assault boats could not approach due to rapid currents. The rescue team deployed three long-endurance drones equipped with turbojet engines, using a ‘point-to-point hover drop’ method to deliver life jackets, emergency lights, and compressed biscuits to people stranded on rooftops. The drones, equipped with millimeter-wave radar, monitored the water flow speed in real-time. Each delivery took 8 minutes, reducing rescue costs by 70% compared to helicopters. Continuous operations for 12 hours provided supplies to 280 people, ensuring the basic survival needs of the isolated villagers.
