Full operations resumed at Newark Liberty International Airport in New Jersey Tuesday evening after nearby drone activity forced a brief suspension of flight arrivals.
An FAA spokesman told multiple outlets that incoming flights were held for about 30 minutes after a drone was spotted flying about 3,500 feet over the nearby Teterboro Airport. Those planes were forced to circle Newark airport until they were given permission to land.
Newark is one of the three main airports that serve the New York City area, with tens of millions of passengers passing through it each year.
Newark officials said they were coordinating with the FAA and law enforcement to investigate Tuesday's incident.
Dozens of drone sightings in the U.K. late last year forced London's Gatwick Airport to cancel or divert about 1,000 flights over the course of three days, affecting roughly 140,000 passengers.
