RAF apologises for sonic boom heard over Norwich
People reported doors and windows shaking
A sonic boom was heard in parts of East Anglia after an RAF jet completed a high-speed dive while on a test flight.
The loud noise was heard over Norwich late on Wednesday morning, with people reporting on social media that doors and windows shook.
An RAF spokesman said: “The sonic boom heard in East Anglia was inadvertently caused by an RAF Hawk aircraft completing a high-speed dive as part of an air test schedule.
“Any inconvenience caused to local residents is regretted.”
A sonic boom is created when an object moves through air faster than the speed of sound, 767mph.
It is the second time a sonic boom has been heard across eastern England this month.
On January 12, a loud noise was heard after two RAF fighter jets were scrambled to intercept a private plane.
An RAF spokesman said at the time that Quick Reaction Alert Typhoon aircraft were launched from RAF Coningsby to intercept a civilian aircraft that had lost communications.
Communications were subsequently re-established and the aircraft was intercepted and safely escorted to Stansted.
