A sonic boom which shook Peterborough this lunchtime was caused by military jets.
Typhoon aircraft from RAF Coningsby were scrambled to intercept a civilian plane which lost radio contact with air traffic control.
A spokesman said for operational reasons they were authorised to go supersonic.
The civilian plane managed to regain contact before the jets arrived.
“The MOD can confirm that Typhoon aircraft from RAF Coningsby were launched from Quick Reaction Alert this afternoon to investigate a civilian aircraft which had lost radio contact with air traffic control," an RAF Coningsby spokesman said.
"The civilian aircraft re-established communication prior to intercept and was released to proceed en route. The Typhoon aircraft were authorised to go supersonic over land for operational reasons, any inconvenience caused to local residents is regretted.”
