Two fighter jets scrambled to intercept a cargo plane caused a sonic boom over south London and Kent today.

The loud bang was heard in Dartford, Sidcup, Sevenoaks and Tonbridge as the RAF Typhoons broke the sound barrier.

The Latvian Antonov 26, lost contact with air traffic controllers on a flight to Birmingham and was escorted to Stansted Airport in Essex.

The fighter jets from RAF Coningsby in Lincolnshire were given special permission to travel at supersonic speeds over mainland Britain.

Essex police said the Antonov landed safely at Stansted where it was established the aircraft posed no threat.

All three people who were on board have been spoken to by police.

Typhoon aircraft were launched this afternoon from RAF Coningsby to intercept a civilian aircraft south of London which was causing concern to air traffic control authorities. The aircraft was safely escorted to London Stansted. To fulfill their quick reaction role the Typhoons were cleared to travel at supersonic speed, any noise disturbance as a result of this is regretted. Essex Police now have the lead.
