A sizable, four-engine civilian drone, laden with Yangcheng Lake hairy crabs, soared into the sky from Chengdu Huaizhou Airport. After one and a half hours of flight, it smoothly touched down at Dazhou Heshi Airport. Subsequently, couriers promptly delivered the crabs to eager consumers. This particular flight embraced a cross-province air-to-air relay approach, following the route of "Jiangsu-Chengdu-Dazhou." This milestone event signifies JD Logistics' accomplishment of a low-altitude logistics verification test flight for main and branch routes in Sichuan. It also stands as a remarkable stride forward since the inauguration of Sichuan's inaugural low-altitude logistics route designed for large drones. This innovative route slashes the freight time between Chengdu and Dazhou to under 2 hours, achieving a reduction of over 50% compared to traditional land transportation. Moreover, it offers an efficient air supply chain solution for perishable goods like fresh produce and critical emergency supplies.
