Hundreds of people in England reported being woken up by a big bang noise at about 4.20am this morning, with some saying their homes shook to the core.
With recent events in London it gave sleepers a large fright but it turned out it was a supersonic boom as two RAF Typhoons were deployed rapidly to the skies as an aircraft over England lost radio control.
An RAF spokesperson said: “Two Typhoon fighter aircraft from RAF Coningsby were scrambled at 0409 this morning as part of the UK’s Quick Reaction Alert procedures after an aircraft lost communications in UK airspace.
“The aircraft was intercepted and its communications were subsequently re-established.”
They added the Typhoons returned to their base afterwards.
The Metropolitan Police said: “The loud bang heard throughout north London and surrounding areas was the result of a sonic boom from RAF planes.”
The Met stated that there was “no cause for concern”.
