Drone sightings force closure of Changi Airport runway, nearly 40 flights affected
"To ensure the safety of aircraft operations and passengers, the operations of one runway were suspended for short periods of time between 11pm on Jun 18 and 9am on Jun 19," said the authority in a statement.
During this time, Changi Airport operated with one runway.
Thirty-seven scheduled departure and arrival flights were delayed, while one arrival flight was diverted to Kuala Lumpur, said CAAS.
Singapore Airlines (SIA) said 19 of its flights - mainly on its Southwest Pacific, Southeast Asia, North Asia and Europe routes - were affected by the runway closure.
The delays in arrivals and departures were between 8 minutes and 33 minutes, SIA added.
"Passengers who needed to make flight connections were assisted accordingly," a spokesperson for the airline said.
"A multi-agency team including the Civil Aviation Authority of Singapore, Changi Airport Group, Singapore Armed Forces and the Singapore Police Force was activated for the search and locate operations," it said.
Investigations are ongoing. ■
