Londoners took to Twitter after a loud "explosion" sound was heard across the capital and beyond. Just after 1pm on Tuesday (January 12), people in Ilford, Greenwich, and even as far away as Essex felt the vibrations of a booming crash. Also known as a "sonic boom", it's believed to have been caused by two RAF Typhoons. It's reported the aircraft were launched from RAF Coningsby to intercept a private jet that lost communications. Mary O'Donnell told MyLondon that the "earth shook below her" after hearing a loud bang in Ilford.

A sonic boom is caused when shock waves are created when an object travels faster than the speed of sound. The unmistakable moment the sonic boom sounded was captured by a CCTV camera in Standon in Hertfordshire belonging to @standona120. During the short footage of a local road in the Standon area a loud bang can suddenly be heard during filming. Did you hear the 'sonic boom'?
