Many took to social media to report the sound of an ‘explosion’, with some saying their house had shaken.

It was heard across London, Hertfordshire, Bedfordshire and Cambridgeshire.

It was caused by two Royal Air Force Typhoons, which had taken off from Coningsby in Lincolnshire to intercept an unresponsive aircraft.

Sonic booms are caused when an aircraft travels faster than the speed of sound.

RAF jets are only cleared to travel at supersonic speeds in emergencies, such as intercepting another aircraft.

The sound was captured on CCTV cameras.

An RAF spokesowman said: “Typhoon aircraft from RAF Coningsby were scrambled this morning, as part of the UK's Quick Reaction Alert (QRA) procedures, after an aircraft lost communications in UK airspace.

“The aircraft was intercepted and its communications were subsequently re-established.”
