(CNN) -- Military fighter planes escorted a Gulfstream jet to the London area's Stansted Airport on Wednesday evening after the jet lost contact with air traffic controllers, an airport spokesman said.
The Gulfstream landed at the airport, about 40 miles outside central London, about 7:45 p.m. local time and was escorted to a remote part of the airfield, Mark Davison said.
At least one flight was delayed as the Gulfstream was escorted to a landing. The airport was reopened after the Gulfstream parked.
Essex police had no immediate comment on the incident.
