The closure lasted for nearly two hours and caused at least two dozen inbound flights to divert to alternate airports.
The airport said it had experienced a problem with its air traffic control systems. A 7 p.m. update from the airport stated that flights had resumed, but suggested that residual delays were expected as the airport worked to bring operations back to normal. "We apologise and advise passengers to check flight info with your airline".

The Guardian reported that the cancellations and delays affected flights in other European cities, including Gothenburg, Sweden; Bilbao, Spain; and Bergen, Norway.
Flights to and from the major airport have been postponed after an issue with its control tower was announced this evening (July 10). Gatwick is the UK's second-busiest airport, and the eighth busiest in Europe.
