An investigation is under way after a passenger plane landed at Gatwick Airport without clearance.
The plane landed despite an air traffic controller instructing the pilot to perform a ‘go around’ due to the runway being in use by another aircraft.
A go-around is a standard safety procedure in which an aircraft approaching an airport breaks off its approach and flies a circuit before landing.
The incident happened at 6.50pm on Monday (January 6).
A spokesman for National Air Traffic Services (NATS) said the crew of the Boeing 737 acknowledged the instruction to “go-around”, but the aircraft continued to land.
It is understood the other aircraft was exiting the runway as the plane came in to land.
The spokesman added: “At the time the aircraft landed the runway was not occupied and safety was not jeopardised at any time.”
The matter is now the subject of an internal NATS investigation.
