People's Liberation Army Air Force (PLAAF) helicopter unit in Hebei detected an illegal low-flying drone yesterday during training and forced it to land.
Preliminary investigations showed the drone was owned by an aerospace technology company in Beijing and the flight was not reported to or approved by the authority, state-run Xinhua news agency reported today.
PLAAF spokesperson Shen Jinke saidillegal flights of low-altitude and slow-speed small aircraft threaten civil aviation safety and public security.
There have also been cases that have disturbed military flight training, the report said.

The aerial vehicles involved include helicopters, drones, model airplanes and delta-wing aircraft, and were owned by private companies, aviation enthusiasts as well as a few airlines.
Any activity in the air must not compromise national aerospace security as well as public and personal safety, Shen said.
Regulations on aviation flight came into force in December 2013, simplifying the application procedures but still requiring approvals for nine kinds of flights.
