"China flight systems jammed by pig farm’s African swine fever defences." That headline from the South China Morning Post sums up this strange story. Gangs in China reportedly send drones to drop material infected with Swine Flu on pig farms. Then, the gangs buy the meat on the cheap and sell it to unwitting customers. (Swine flu rarely passes to humans.) From the South China Morning Post:
The farm, in northeastern China, was ordered last month to turn in an unauthorised anti-drone device installed to prevent criminal gangs dropping items infected with the disease, according to online news portal Thepaper.cn.
The device came to light after a series of flights to and from Harbin airport complained about losing GPS signals while flying over Zhaozhou county in Heilongjiang in late October. In some cases, the ADS-B tracking technology – which determines an aircraft’s position via satellite navigation – failed.
