According to official information, two RAF fighter jets triggered the sonic boom in parts of England this afternoon.
The two jets of RAF Coningsby in Lincolnshire were jumbled up to intercept a private plane.
The plane had lost communication and was being transferred to Stansted Airport in London.
The hashtag #sonicboom was trending on Twitter after numerous reports of a loud bang in Cambridgeshire, Essex, Suffolk and London.
The jets are often used to escort aircraft that lose contact with air traffic control or do not respond to communication.
Reports flooded social media after hearing the boom. Some said he even made their homes shake.
One reported a “mighty bang”.
The flight tracking website ADSBexchange.com recorded a Eurofighter Typhoon FGR4 reaching a top speed of more than 1,150 km / h over Ickleton, south of Cambridge.
A sonic boom occurs when an object moves through the air faster than the speed of sound of 767 miles per hour, which the jet first surpassed near Peterborough.
Sam Harrison captured the moment with her doorbell camera in Hornchurch, east London.
“At first I thought it was either an explosion or an earthquake … I ran outside expecting a lot of smoke,” they told the PA news agency.
An RAF spokesman said: “The RAF can confirm that rapid reaction alert typhoon planes were launched by RAF Coningsby this afternoon to intercept a civilian plane that had lost communication.
“Communication was then restored, the aircraft intercepted and safely escorted to Stansted.
“The Typhoon aircraft were allowed to fly at supersonic speed for operational reasons.”
