Flights to and from the Spanish capital's international airport Adolfo Suárez-Barajas were disrupted for over one hour today after Enaire, Spain's air navigation authority, reported the possible presence of drones in the vicinity.
Two airline pilots reportedly spotted drones near the airport.
An Air Canada flight has had to make an emergency landing at the airport after its landing gear was damaged. It's not thought that the incident is related to the supposed drone disruption earlier in the day.
The airport manager AENA confirmed that 26 flights were diverted to other airports by the time air traffic restrictions were lifted.
