On June 18th 2019, Changi airport was forced to temporarily suspend operations from one of the two runways after confirmed sighting of a drone flying close to the Southeast Asian hub.

For the safety of the aircraft and passengers the runway was closed from 11 p.m. until the 9 a.m. the following morning. The airport continued operating with the second runway during that suspension. That caused delays to 37 departures and arrivals of flights and one was diverted to Kuala Lumpur.

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, and will not hesitate to take enforcement action against those who contravene regulations.
