It is the first prosecution of individuals under a law regulating drone use, said Josephus Tan from Invictus Law Corporation, who is representing the men. The first case against a company was launched in May, local media reports said. According to the Civil Aviation Authority of Singapore, a permit is required when using drones for recreational purposes within five kilometres of an airport or military airbase, or flying them at altitude of over 200 feet (60 metres). The men face a fine of up to Sg 20,000 ( 14,700) if convicted. Drones are more and more frequently causing havoc for air traffic around the world. As well as Singapore’s Changi Airport, London’s Gatwick and Heathrow and a string of other major hubs have been affected.
