Tech used in flood control, disaster relief

Unmanned aircraft

China deployed unmanned aircraft to restore communication services and survey conditions in several parts of Central China's Henan province that were severely affected by recent heavy rain and flooding.

A Wing Loong 2H disaster-assistance drone took off on the afternoon of July 21 from the Anshun airport and flew nearly 1,200 kilometers before arriving over Henan's Mihe township. The aircraft then began to fly around the flood-stricken township to provide communication links to people using the China Mobile network.
