Operations at Changi Airport in Singapore have been disrupted for the second time due to unauthorised drone activity in the area.
The Civil Aviation Authority of Singapore (CAAS) said that about 15 departures and three arrivals were delayed on 24 June, while an additional seven flights were diverted. Bad weather was also reported as a factor in the disruptions.
Arrivals and departures were carefully regulated for short periods of time as a precautionary measure.
Last week, one runway was suspended at Changi Airport and several flights were delayed after drone sightings. An arrival flight was also diverted to Kuala Lumpur, Malaysia.
CAAS said in a statement: “Members of the public are reminded that the authorities take a serious view of errant operations of unmanned aircraft which may pose threats to aviation or endanger the personal safety of others.”
The agency said investigations are ongoing and offenders could face fines of up to S$20,000 ($14,780) or 12 months in prison.
Airports across the world are facing a growing security concern due to an increase in the availability of drones.
In December 2018, drone sightings caused about 36 hours of travel chaos at London’s Gatwick Airport, leading to the cancellation or diversion of around 1,000 flights at an estimated cost of over £50m.
In March 2019, an illegal drone was spotted flying near Frankfurt Airport in Germany, forcing operator Fraport to suspend all landings and take-offs for 30 minutes as a precautionary measure to safeguard passengers.
